gtk compile problem - parse error

[John Vestrum <vestrum msi umn edu>]

I'm compiling gtk+ 2.6.8 on Solaris 9 with gcc 3.3.2. I installed glib, pango, atk, and fontconfig without any trouble, and the ./configure for gtk+ compeletes successfully. The gmake fails, however, with a parse error before "XTrapezoid" in gdkdrawable-x11.h (full error below). Anyone know what is going on here?

Error from gmake:
