Trying to get AHI V6 to compile with GCC V2.95

Can anyone help with these GCC compiler issues?

I've been using gcc v3.3 to compile AHI without any problems but now I've gone back to v2.95 it's giving me grief


The problem is with the ahi header file (V6), the compiler complains about 'inline/ahi.h' with the following message:

'ahi.h: 29 badly punctuated parameter list in #define'


This is the line in question

Code:
#ifndef NO_INLINE_STDARG
#define AHI_AllocAudio(___tag1, ...) \
({_sfdc_vararg _tags[] = { ___tag1, __VA_ARGS__ }; AHI_AllocAudioA((struct TagItem *) _tags); })
#endif /* !NO_INLINE_STDARG */
After comparing it to the NDK 3.5 files, it looks like it should be written something like this instead:

Code:
#ifndef NO_INLINE_STDARG
#define AHI_AllocAudio(tags...) \
({ULONG _tags[] = {tags}; AHI_AllocAudioA((struct TagItem *) _tags); })
#endif /* !NO_INLINE_STDARG */
Should I update the ahi header file as above or is there an easier way?

I think there is not much you can do (maybe somebody comes up with a clever #define). The first version is C99 (implemented in v3.3), the second version is gcc's own syntax for variadic macros.

Interesting, looks like it's a C++ issue as it seems to compile and link fine using plain old C in 2.95.3
