19  * History:
20  * 21-May-2000 BS       - Fixed the ident requirement of resource names
21  *                        which can be keywords.
22  * 30-Apr-2000 BS       - Reintegration into the wine-tree
23  * 11-Jan-2000 BS       - Very drastic cleanup because we don't have a
24  *                        preprocessor in here anymore.
25  * 02-Jan-2000 BS       - Removed the preprocessor code
26  * 23-Dec-1999 BS       - Removed the copyright for Martin von Loewis.
27  *                        There is really nothing left of his code in
28  *                        this parser.
29  * 20-Jun-1998 BS       - Changed the filename conversion. Filenames are
30  *                        case-sensitive inder *nix, but not under dos.
31  *                        default behaviour is to convert to lower case.
32  *                      - All backslashes are converted to forward and
33  *                        both single and double slash is recognized as
34  *                        MS/Borland does.
35  *                      - Fixed a bug in 'yywf' case that prevented
36  *                        double quoted names to be scanned propperly.
37  *
38  * 19-May-1998 BS       - Started to build a preprocessor.
39  *                      - Changed keyword processing completely to
40  *                        table-lookups.
41  *
42  * 20-Apr-1998 BS       - Added ';' comment stripping
43  *
44  * 17-Apr-1998 BS       - Made the win32 keywords optional when compiling in
45  *                        16bit mode
46  *
47  * 15-Apr-1998 BS       - Changed string handling to include escapes
48  *                      - Added unicode string handling (no codepage
49  *                        translation though).
50  *                      - 'Borrowed' the main idea of string scanning from
51  *                        the flex manual pages.
52  *                      - Added conditional handling of scanning depending
53  *                        on the state of the parser. This was mainly required
54  *                        to distinguish a file to load or raw data that
55  *                        follows. MS's definition of filenames is rather
56  *                        complex... It can be unquoted or double quoted. If
57  *                        double quoted, then the '\\' char is not automatically
58  *                        escaped according to Borland's rc compiler, but it
59  *                        accepts both "\\path\\file.rc" and "\path\file.rc".
60  *                        This makes life very hard! I go for the escaped
61  *                        version, as this seems to be the documented way...
62  *                      - Single quoted strings are now parsed and converted
63  *                        here.
64  *                      - Added comment stripping. The implementation is
65  *                        'borrowed' from the flex manpages.
66  *                      - Rebuild string processing so that it may contain
67  *                        escaped '\0'.
