Another possibility is there is some fundamental difference between the
first and second forms of TRY_COMPILE so that the second form avoids the
infinite recursion while the first one does not.  An earlier version of
my Ada support simply did a compile test with gcc -c with the second
TRY_COMPILE form, and that did not have the infinite recursion problem
encountered when I attempt to use the first form of TRY_COMPILE with
a full compile+bind+link test with gnatmake.

Anyhow, with the gnatmake test, the first form of TRY_COMPILE is required,
and so far I have not been able to figure out how to avoid the infinite
TRY_COMPILE issue with that form.  Thus, I would really appreciate an
answer for how that issue is avoided for the second TRY_COMPILE form
for C, C++, Fortran, and a compile-only Ada test.
