Currently, x11-wm/fbpager doesn't compile with gcc-4.2 as found in
recent -CURRENT:

Fix: The patch below was taken from Gentoo Linux Bugzilla, originally
submitted by Ryan Hill. See http://bugs.gentoo.org/135504

It fixes the build with gcc-4.2 for me.

	
How-To-Repeat: On a -CURRENT box with gcc-4.2:

# cd /usr/ports/x11-wm/fbpager
# make
