Tests fail using Apple's LLVM

[Corin Lawson]

Hi,

Thanks for your good work on GMP, I'll try and include all the info I can
in this bug report. Maybe it has something to do with Apple's LLVM
compiler...

UPDATE: Having compiled all the info below I thought to try `CC=gcc-4.2
./configure` and all the tests pass now. Maybe you can add a quick fix to
the configure script. Thanks.

PLEASE DISREGARD BELOW

STEPS TO REPRODUCE

1. Download gmp-5.0.2.tar.bz2<ftp://ftp.gmplib.org/pub/gmp-5.0.2/gmp-5.0.2.tar.bz2>
and
unpack
2. ./configure && make
3. make check

EXPECTED OUTPUT

PASS all tests and exit

ACTUAL OUTPUT

Last few lines are:

PASS: t-tdiv_ui
PASS: t-fdiv
PASS: t-fdiv_ui
PASS: t-cdiv_ui

I left it for a day but it never exits; process called t-gcd uses a
significant amount of CPU.

Control-C outputs this:

make[4]: *** [check-TESTS] Interrupt: 2
make[3]: *** [check-am] Interrupt: 2
make[2]: *** [check-recursive] Interrupt: 2
make[1]: *** [check-recursive] Interrupt: 2
make: *** [check] Interrupt: 2

Killing the offending process(es) gives the following fails (I gave each
test at least 2 mins of CPU time):

Not sure why it gives a summary twice...
