#  GNOME_SRCS: are gnome only sources

# OBJS is for flavor independent files

# Basically take the output foo.d file and put it in the right
# subdirectory, adding a prefix indicating where the file actually
# lives (i.e. obj-pic/Foo.cc rather than Foo.cc.  This would all be
# unnecessary if gcc actually paid attention to the argument to "-o".

# Note that this cannot handle subdirs in the Makefile dir, so if the
# relevant Makefile was src/foo/Makefile, this rule can't handle
# src/foo/bar/x.c src/foo/x.c and src/foo/bax/x.c.  You'd need another
# Makefile in src/foo/bar and src/foo/bax for now.
