BUG!! gcc-2.95.3 (`__builtin_va_alist' undeclared in snprintf()) on Solaris-2.5.1

[Auteria Wally Winzer Jr.]

Is it possible gcc-2.95.3 is broken? It seems so.
Here's output using the "-H" option to gcc
(NOTE: this problem doesn't exist w/ 2.95.2):

../dist/../clib/snprintf.c:47: for each function it appears in.)
make: *** [snprintf.o] Error 1

Maybe during the compilation fixincludes failed.  Is there another way of
fixing the includes during compilation of 2.95.3?
