Yes, however, vala-gen-introspect includes a full C parser. While the
resulting bindings might not be very useful, it can parse non-GObject
header files equally well. If you get a syntax error, it's either a bug
in the header file or in the parser.

Alternatively, you could try using the new gobject-introspection
infrastructure for this, it contains an updated version of the C parser
among other things. vapigen can deal with the new .gir format, although
there is still some work needed.
