 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.
