Thanks. It's a problem in the bundled c2hs. I'll investigate a fix.
Santiago, if you're in the mood for testing, would you mind trying this pre-release tarball? I think I've fixed it. http://haskell.org/gtk2hs/gtk2hs-0.9.10.4.tar.gz
I couldn't try till now, so I had to try 0.9.11 I got a different error: make[3]: Entering directory `/var/tmp/portage/dev-haskell/gtk2hs-0.9.11/work/gtk2hs-0.9.11' ./tools/c2hs/c2hsLocal +RTS -RTS -C-I/usr/include/glib-2.0 -C-I/usr/lib64/glib-2.0/include --cppopts='-include "gtk2hs-config.h"' --precomp=glib/glib.precomp glib-object.h In file included from /usr/include/glib-2.0/glib/gstring.h:32, from /usr/include/glib-2.0/glib/giochannel.h:32, from /usr/include/glib-2.0/glib.h:47, from /usr/include/glib-2.0/gobject/gtype.h:26, from /usr/include/glib-2.0/gobject/gboxed.h:26, from /usr/include/glib-2.0/glib-object.h:25: /usr/include/glib-2.0/glib/gutils.h:381:1: warning: "GLIB_CHECK_VERSION" redefined In file included from <command line>:1: ./gtk2hs-config.h:140:1: warning: this is the location of the previous definition c2hsLocal: Error in C header file. /usr/include/glib-2.0/glib/gutils.h:278: (column 26) [FATAL] >>> Syntax error!

Cheers. In the mean time I've fixed up c2hs so it can parse absolutely everything (the whole kernel and system packages). Unfortunately Gtk2Hs is using a fork of c2hs so some more work is required to get Gtk2Hs fixed.
It's fixed upstream hopefully now. Just waiting for a final 0.9.12 release. If you want to try the pre-release tarball, it's here: http://haskell.org/gtk2hs/gtk2hs-0.9.11.3.tar.gz
gtk2hs-0.9.12 is in portage. Hopefully this fixes the problem. Can someone please test and confirm? It works for me, but then I never experienced the original problem.
Builds for me now, the bug was about it not building. Last build was glibc-2.5-* and gcc-4.2, so it seems this version is prepared for the close future :)
Excellent, thanks Santiago :-) I'll close the bug then.
