All,

I thought I should update to GCC 3.1 seeing how yesterday it was available
from the v2gnu directory on Simtel. I have not gotten to the bottom of this
yet, but so far GCC 3.1 gives the following error when building the CVS
LIBC. I did a CVS LIBC refresh yesterday afternoon (now morning in OZ) to
ensure I had the latest files.

d:/dj204/bin/make.exe -C ansi/stdio

gcc ... -c fprintf.c
cc1.exe: warnings being treated as errors

It looks like the definition of __builtin_va_list has changed between GCC
3.04 and 3.1 as the code built okay with 3.04 from early last month. The
va_list is defined in include\sys\djtypes.h as follows:-

/* For GCC 3.00 or later we use its builtin va_list.
*/
/* In most cases these definitions won't be used, because headers provided
*/
/* by GCC hide them. But we can DTRT if GCC headers are missing.
*/
#if __GNUC__ >= 3
#define __DJ_va_list    typedef __builtin_va_list va_list;
#else
#define __DJ_va_list typedef void *va_list;
#endif

Any ideas on fixing this one?

Andrew
