gtkmathview-0.8.0 fails to build with GCC 4.4 due to a missing include. The attached patch adds the necessary header.
Created attachment 189421 [details, diff] Patch to add the missing headers.
+ 10 May 2009; Samuli Suominen <ssuominen@gentoo.org> + gtkmathview-0.8.0.ebuild, +files/gtkmathview-0.8.0-gcc44.patch: + Fix compile with GCC 4.4 wrt #267472, thanks to John Keeping. But I'm leaving this bug open in case gnome@ wants to take some extra steps (like, forward this to upstream).
This is already in upstream svn: http://svn.gnome.org/viewvc/gtkmathview/trunk/src/common/AbstractLogger.cc?r1=1177&r2=1183
