Hi,
since I'm working on some new packages for Fink that depends on gmp
I've noticed that gmp's developers claim that there are quite a lot
of problems in compiling that library correctly. They recommend to
run "make check" after compilation and don't trust the library if it
doesn't pass all checks. In particular Apple's gcc is reported to be
one of the compiler that miscompiles the library.
Worried by these claims, I've tried to build gmp on my local tree to
verify if the library passes the tests or not. It turns out that it
doesn't! No matter which compiler's version I choose (i.e., 4.0, 3.3,
3 for both gcc and g++, [1]) 'make check" always fails at the same
test. I've also tried to update gmp from version 4.1.3 (avaible on
the Fink's unstable tree) to the latest upstream version (4.1.4), but
the same test fails.
Here it is the meaningful part of the check process:

===================
I'm not a linking and library expert, so probably I'm wrong here, but
it seems that the warning raised by the linker about the multiple
definitions of the symbol _localeconv should be the reason of the
failure. So I've started wondering whether the gmp library
distributed with Fink can be trusted or not, and if not how it can be
fixed.
As a final note I'd like to stress that I tried to build gmp without
the --enable-cxx configure's flag and the library compile correctly
and passes all the tests.
HTH,
Andrea
[1]: In the original .info file the GCC field is set to 3.3. However
SetCC and SetCXX fields are not present so the library is compiled
using version 4.0 of the compiler. If the library is supposed to be
compiled with gcc-3.3, those fields must be added.
