I have applied patches 2, 3, and 4. For patch 1, I changed the 'long long' in va_arg() to a typedef for 'long long'. Let me know if that fixes it. > Gentlemen: > I have tested today's snapshot (retrieved this morning) > on an SGI Irix 6.2 system with the following results: > > 1) The int8 test still fails because the SGI C compiler does > not handle a variable argument declaration of "long long" correctly in > the definition of the function dopr in snprintf.c.
