c2ada and SWIG are two projects in this area. I wouldn't recommend c2ada
(although I am at present a developer), because at some point before the
migration to Sourceforge someone had the grand idea of translating C
bodies as well as headers, but failed to carry it through. Haven't used
SWIG.

As Jacob says, GNAT includes this ability. As I recall, the generated
code will be OS-specific; provided the original headers were reasonably
sane this should be OK.
