Building error with gmessages.h on Gnome 2/S9.

Hi all,
I'm now using Sun Forte 6U1 on S9 with Gnome 2 installed to build
a gnome application. The application builds ok using gcc-3.2.
But when I use Forte 6U1 CC to build it, it fails for compiling 
gmessage.h:

~/>which CC

"/usr/include/glib-2.0/glib/gmessages.h", line 122: Error: Identifier list

Since gmessages.h is a basic gnome header, did anybody see the problem before?
I didn't install any Forte 6U1 CC patches. Seems that it's a problem with Forte
6U1
CC itself. Is there any patches available ? Could you give any comments for
investigation ?

Thanks.
