 Changes in GMP 4.2.3
 Bugs:
 Fix x86 CPU recognition code to properly identify recent AMD and Intel
 64-bit processors.
 The >> operator of the C++ wrapper gmpxx.h now does floor rounding, not
 truncation.
 Inline semantics now follow the C99 standard, and works with recent GCC
 releases.
 C++ bitwise logical operations work for more types.
 For C++, gmp.h now includes cstdio, improving compiler compatibility.
 Bases > 36 now work properly in mpf_set_str.
 Speedups:
 None, except that proper processor recognition helps affected processors.
 Features:
 The allocation functions now detect overflow of the mpz_t type. This means
 that overflow will now cause an abort, except when the allocation
 computation itself overflows. (Such overflow can probably only happen in
 powering functions; we will detect powering overflow in the future.)
