 * History:
 * 24-Jul-2000 BS       - Made a fix for broken Berkeley yacc on
 *                        non-terminals (see cjunk rule).
 * 21-May-2000 BS       - Partial implementation of font resources.
 *                      - Corrected language propagation for binary
 *                        resources such as bitmaps, icons, cursors,
 *                        userres and rcdata. The language is now
 *                        correct in .res files.
 *                      - Fixed reading the resource name as ident,
 *                        so that it may overlap keywords.
 * 20-May-2000 BS       - Implemented animated cursors and icons
 *                        resource types.
 * 30-Apr-2000 BS       - Reintegration into the wine-tree
 * 14-Jan-2000 BS       - Redid the usertype resources so that they
 *                        are compatible.
 * 02-Jan-2000 BS       - Removed the preprocessor from the grammar
 *                        except for the # command (line numbers).
 *
 * 06-Nov-1999 JS       - see CHANGES
 *
 * 29-Dec-1998 AdH      - Grammar and function extensions.
 *                           grammar: TOOLBAR resources, Named ICONs in
 *                              DIALOGS
 *                           functions: semantic actions for the grammar
 *                              changes, resource files can now be anywhere
 *                              on the include path instead of just in the
 *                              current directory
 *
 * 20-Jun-1998 BS       - Fixed a bug in load_file() where the name was not
 *                        printed out correctly.
 *
 * 17-Jun-1998 BS       - Fixed a bug in CLASS statement parsing which should
 *                        also accept a tSTRING as argument.
 *
 * 25-May-1998 BS       - Found out that I need to support language, version
 *                        and characteristics in inline resources (bitmap,
 *                        cursor, etc) but they can also be specified with
 *                        a filename. This renders my filename-scanning scheme
 *                        worthless. Need to build newline parsing to solve
 *                        this one.
 *                        It will come with version 1.1.0 (sigh).
 *
 * 19-May-1998 BS       - Started to build a builtin preprocessor
 *
 * 30-Apr-1998 BS       - Redid the stringtable parsing/handling. My previous
 *                        ideas had some serious flaws.
 *
 * 27-Apr-1998 BS       - Removed a lot of dead comments and put it in a doc
 *                        file.
 *
 * 21-Apr-1998 BS       - Added correct behavior for cursors and icons.
 *                      - This file is growing too big. It is time to strip
 *                        things and put it in a support file.
 *
 * 19-Apr-1998 BS       - Tagged the stringtable resource so that only one
 *                        resource will be created. This because the table
 *                        has a different layout than other resources. The
 *                        table has to be sorted, and divided into smaller
 *                        resource entries (see comment in source).
 *
 * 17-Apr-1998 BS       - Almost all strings, including identifiers, are parsed
 *                        as string_t which include unicode strings upon
 *                        input.
 *                      - Parser now emits a warning when compiling win32
 *                        extensions in win16 mode.
 *
 * 16-Apr-1998 BS       - Raw data elements are now *optionally* separated
 *                        by commas. Read the comments in file sq2dq.l.
 *                      - FIXME: there are instances in the source that rely
 *                        on the fact that int==32bit and pointers are int size.
 *                      - Fixed the conflict in menuex by changing a rule
 *                        back into right recursion. See note in source.
 *                      - UserType resources cannot have an expression as its
 *                        typeclass. See note in source.
 *
 * 15-Apr-1998 BS       - Changed all right recursion into left recursion to
 *                        get reduction of the parsestack.
 *                        This also helps communication between bison and flex.
 *                        Main advantage is that the Empty rule gets reduced
 *                        first, which is used to allocate/link things.
 *                        It also added a shift/reduce conflict in the menuex
 *                        handling, due to expression/option possibility,
 *                        although not serious.
 *
 * 14-Apr-1998 BS       - Redone almost the entire parser. We're not talking
 *                        about making it more efficient, but readable (for me)
 *                        and slightly easier to expand/change.
 *                        This is done primarily by using more reduce states
 *                        with many (intuitive) types for the various resource
 *                        statements.
 *                      - Added expression handling for all resources where a
 *                        number is accepted (not only for win32). Also added
 *                        multiply and division (not MS compatible, but handy).
 *                        Unary minus introduced a shift/reduce conflict, but
 *                        it is not serious.
 *
 * 13-Apr-1998 BS       - Reordered a lot of things
 *                      - Made the source more readable
 *                      - Added Win32 resource definitions
 *                      - Corrected syntax problems with an old yacc (;)
 *                      - Added extra comment about grammar

         * This extra rule fixes it.
         * The problem is that the expression handling rule "expr: xpr"
         * is not reduced on non-terminal tokens, defined above in the
         * %token declarations. Token tNL is the only non-terminal that
         * can occur. The error becomes visible in the language parsing
         * rule below, which looks at the look-ahead token and tests it
         * for tNL. However, byacc already generates an error upon reading
         * the token instead of keeping it as a lookahead. The reason
         * lies in the lack of a $default transition in the "expr : xpr . "
         * state (currently state 25). It is probably omitted because tNL
         * is a non-terminal and the state contains 2 s/r conflicts. The
         * state enumerates all possible transitions instead of using a
         * $default transition.
         * All in all, it is a bug in byacc. (period)

/*
 * This gets invoked to determine whether the next resource
 * is to be of a standard-type (e.g. bitmaps etc.), or should
 * be a user-type resource. This function is required because
 * there is the _possibility_ of a lookahead token in the
 * parser, which is generated from the "expr" state in the
 * "nameid" parsing.
 *
 * The general resource format is:
 * <identifier> <type> <flags> <resourcebody>
 *
 * The <identifier> can either be tIDENT or "expr". The latter
 * will always generate a lookahead, which is the <type> of the
 * resource to parse. Otherwise, we need to get a new token from
 * the scanner to determine the next step.
 *
 * The problem arrises when <type> is numerical. This case should
 * map onto default resource-types and be parsed as such instead
 * of being mapped onto user-type resources.
 *
 * The trick lies in the fact that yacc (bison) doesn't care about
 * intermediate changes of the lookahead while reducing a rule. We
 * simply replace the lookahead with a token that will result in
 * a shift to the appropriate rule for the specific resource-type.
