first spin of trial patch

How about if we make building the plugin conditional on having c99 available? 
I'm testing this at the moment on cygwin, and will test it later on linux;
Sean, could you give it a try on SPARC and check that it successfully disables
building the plugin?  (Don't forget to regenerate the two configure files, I
omitted that diff from the patch.  If you'd prefer, I could send a version with
the full diff; just ask if so.)
