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

["Auteria Wally Winzer Jr." <wally dot winzer at ChampUSA dot COM>]

Here's the same output using 2.95.2, which I compiled exactly the same as
2.95.3:

The key 2 lines is:

/usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/2.95.2/include/stdarg.h
  /usr/local/lib/gcc-lib/sparc-sun-solaris2.5.1/2.95.2/include/va-sparc.h

which didn't produce the same output from 2.95.3.  It should be
2.95.3/include/stdarg.h/va-sparc.h, but no go.  So it looks as if
fixincludes broke during the compilation, or there's a serious bug.

What can change between 2.95.2 and 2.95.3 w/ fixincludes that can
cause this behavior to occur?

Until a fix is done I have no choice but to revert back to 2.95.2.
