GNAT GPL 2005 provides 'gprmake', which you run instead of gnatmake.
You can then add C (not C++, I think) files (that is, directories
containing *.c files) to your GNAT project files, and gprmake compiles
the C code into a library, then calls gnatmake to build the Ada main,
automatically linking in the C library. Very convenient.

However, 'gprmake' does not appear in the "super secret" GNAT
documentation, so I guess it qualifies as "top secret" :). GPS may use
it transparently; I don't use GPS.
