well http://bugzilla.redhat.com/498964#c1 seems to recommend
  for i in -I/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/include{,/linux}; do
      java_inc="$java_inc $i"
  done
  %configure CPPFLAGS="$java_inc"

But I'm afraid that this might not work with gcj or java-1.7.0-opejdk
(if it existed).

Ideally, I would have a solution general for all the javas, e.g.

BuildRequires: java-devel
%build
for i in -I/usr/include/java{,/linux}; do
      java_inc="$java_inc $i"
done
%configure CPPFLAGS="$java_inc"

where /usr/include/java would be an alternatives-handled symlink.

Id that idea too wild?  Is there anything a java-illiterate Fedora
packager can do to maka it happen?
