See "Debugging" in the manual.

I don't know how to increase it on mingw, but you can use
--disable-alloca as outlined in the manual.

Not sure.  Quite a bit probably.

There shouldn't be, not other than stack size and available memory.

You can probably use a mingw DLL with that, as described in "Notes for
Particular Systems" under MS Windows.

I don't think gmp will build directly with the borland tools, but
maybe there's someone on the gmp-discuss list who has managed.

No, gmpxx.h comes with the same sort of C calls you could write
yourself, just a friendlier syntax.
