You'd probably have better luck asking about this on an anjuta
specific list.  My guess is that there's probably a 'regnerate build
system' button somewhere.

If you're not having any luck, I'd close anjuta. Add the source file
by hand to the Makefile.am (I believe it is...) and run automake or
whatever it is that regenerates the Makefile.in files I think.

Its been quite a long time since I've actually tried using autotools
as a build system, so that last paragraph may or may not make sense.

I do realize you're working with an existing project, but for future
reference you should check out SCons.  Its my build tool of choice and
I have to be a zealot whenever build systems are mentioned...
