Might you consider (I verified it works):
#if defined (_MSC_VER)
#pragma warning(push)
#pragma warning(disable: 4146) // unary minus operator applied to unsigned
type, result still unsigned
#endif
*__gmp_rp = (- *__gmp_up) & GMP_NUMB_MASK;
#if defined (_MSC_VER)
#pragma warning(pop)
#endif

There is some sort of sick competition between certain compilers to have
the most warnings for valid C. I don't think we should play their game,
and as a result obfuscate the GMP sources.

Should not

Let's please not do this.

Minor issue #2 (I should have reported this years ago, sorry):
In gmp.h, these lines:
mpn_neg (mp_ptr __gmp_rp, mp_srcptr __gmp_up, mp_size_t __gmp_n)
[...]
*__gmp_rp = (- *__gmp_up) & GMP_NUMB_MASK;

Hi,
I'm using GMP 6.2. Has been working fine for 2+ years now, great library.
I've built the library (64-bit) using Cygwin. This creates a DLL and a
gmp.h file that can be used with Microsoft Visual Studio C compiler.
As you probably know, MSVC strangely defines long as 32-bits.
In gmp.h,
