Other .c files should not define INLINE.
+ For Emacs, this is done by having emacs.c first '#define INLINE
+ EXTERN_INLINE' and then include every .h file that uses INLINE.
+
+ The INLINE_HEADER_BEGIN and INLINE_HEADER_END suppress bogus
+ warnings in some GCC versions; see ../m4/extern-inline.m4.
C99 compilers compile functions like 'incr' as C99-style extern
- inline functions. Pre-C99 GCCs do something similar with
- GNU-specific keywords. Pre-C99 non-GCC compilers use static
+ inline functions. Buggy GCC implementations do something similar with
+ GNU-specific keywords. Buggy non-GCC compilers use static
functions, which bloats the code but is good enough. */
