Re: GTK+ (embarrassing) Makefile question...

[Christian Seberino <seberino spawar navy mil>]

I think I just got it.  When I add 2 things on same rule line
/your way/ it seems to only "catch" files that have both a .cpp AND .h
version.  It seems that .cpp files with NO .h analog EACH
need a separate rule for them. Ahhhh!!!!
