jextract woes

[Michael Zucchi]

I'm using the github repoistory, foreign-jextract branch if that 
matters.  While tracking that gnu make problem I ended up checking that 
out because I didn't want to wait for mercurial again and I wasn't sure 
if something was broken locally.

By default it can't find system includes:

If I use gcc to pre-process it first:
