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

[Auteria Wally Winzer Jr.]

I backed up /usr/include/varargs.h and /usr/include/sys/varargs.h so that gcc
only finds /usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/2.95.3/include/varargs.h.
I even added the "-v" option to gcc to spit out more detailed output.

Here's the results (test compilation of db-3.3.4):

Same problem.
