I'll check it on Solaris 8 later today. According to the man page of the 
compiler it says:

"If you specify -xc99 without any values, the option is set to -xc99=all."

A small c-programm is being compiled on Solaris 9:

file main.c:
int main()
{
        // nix
}

If I compile this file on Solaris 9 it looks like this:

admin@sun-install ~ > cc -xc99 main.c
cc: -xc99=lib is not available on SunOS 5.9
admin@sun-install ~ >

So it looks that the "=lib" is substituted by the compiler itself. The 
correct flags for Solaris 9 would are:

admin@sun-install ~ > cc -xc99=all,no_lib main.c
admin@sun-install ~ > echo $?
0


and it works :o) So I think it would be ok to add the patch to fix the 
Solaris support. It still should work on Solaris 10 and 
OpenSolaris/Express could someone test it?


A look into the manpage offers following:

NOTE:
Though the compiler support-level defaults to the
language features of the C99 standard, the standard
headers provided by Solaris 8 and Solaris 9 in
/usr/include do not conform with the 1999 ISO/IEC C
standard. If you encounter error messages, try using
-xc99=none to obtain the 1990 ISO/IEC C standard
behavior for these headers.

The 1999 C standard library semantics of routines that
appeared in both the 1990 and 1999 C standard are not
available and therefore cannot be enabled on Solaris 8

and Solaris 9. The compiler issues an error message
when -xc99=lib has been specified directly or
indirectly on Solaris 8 or Solaris 9.
