Christopher, GCC goes out of its way to guarantee data compatibility and
calling sequence compatibility with the native C compilers in a given
configuration. If you ever find a case where there is an incompatibility,
then GCC considers it a bug, and you should report it to the GCC mailing
list as a bug. We know of no such bugs currently in any of the several
hundred configurations supported by GCC.
So When I say that GNAT's calling approach is compatible with C, I really
mean that, I don't just mean it is compatible with GCC. Of course there is no
guarantee that there is not a bug, but bugs can appear anywhere, and it
definitely would be considered to be a bug if GNAT passed a record by
value where C would pass it by address. If you find such a case, report
it as a bug!
