Hmmm, GIMP-1.0 was released the better part of a year ago.
So you are talking about rather out-of-date code.

You wouldn't have these problems at all if the Makefiles
used gtk-config (see docs/gtk-config). But wait, the GIMP 
includes the very cool gimptool script for compiling plugins...

Generally, you can just compile a plugin with

 gimptool plugin.c

Again, this is a very old change. If you look in the GTK+ ChangeLogs 
you'd find a mention of this. But I think you should expect
trying to compile code written before the first public releases
of GTK+ and the GIMP to be a bit of an excercise in archeology.
