Subject: [PATCH] Add an explicit -lm to the link lines in Makefile.gtk, after
 two users reported on the same day that this is now necessary since
 up-to-date GNU tools won't consider it sufficient to have libm be a
 dependency of other explicitly referenced libraries if you're directly
 referring to the contents of libm yourself.
