How to use gmp_version, mpir_version, and mp_bits_per_limb

[ErichSt]

I'm getting "unresolved external symbol __mpir_version referenced" when trying to use "mpir_version" as documented in 3.9 Useful Macros and Constants.

Am I doing something wrong? An uppercase "MPIR_VERSION" seems to work.

Similar issue "unresolved external symbol __gmp_version referenced" for "gmp_version"; again "GMP_VERSION" seems to work.

"mp_bits_per_limb" too isn't working for me, and here the uppercased name doesn't work either.

I must admit, I don't understand why we have the following

#define gmp_version __gmp_version

__GMP_DECLSPEC extern __gmp_const char * __gmp_const gmp_version;

That looks wrong to me. But on the other hand, there are external libraries that use it just fine. I'm not sure how.

Apparently you are supposed to use __gmp_version, etc.

That gives you the version according to the .h file, but not according to the library.

Same here. Apparently it is intended that you use __gmp_bits_per_limb.

I don't know why this doesn't match the documentation. Something seems wrong somewhere.

What's odd is that we define these in precisely the same way as GMP does. It must be correct, but I don't see how to use them.
