gcc and stdarg.h

[Jonathan Claggett]

Hello, this should be a quick #include question. I am attempting to
compile a c program which uses va_start and other stdarg macros on a
Solaris 2.5.1 box. The compile fails because gcc has no knowledge of the
builtin function prototyped in stdarg.h called __builtin_va_alist. Sun's
cc works fine with this builtin. Should I have installed a gcc friendly
stdarg at some point here?

Thank you for your help,
Jonathan Claggett
