25 /* Provide forward declarations of core types which are referred to by
26 most of the compiler. This allows header files to use these types
27 (e.g. in function prototypes) without concern for whether the full
28 definitions are visible. Some other declarations that need to be
29 universally visible are here, too.
31 In the context of tconfig.h, most of these have special definitions
32 which prevent them from being used except in further type
33 declarations. This is a kludge; the right thing is to avoid
34 including the "tm.h" header set in the context of tconfig.h, but
35 we're not there yet. */
