mpfr4 package

mpfr is not compiled with --enable-thread-safe, and so crashes multi-threaded programs

Bug Description

Please compile MPFR with --enable-thread-safe during ./configure. Thread safety is not turned on by default, since MPFR supports multiple platforms, and some can't handle threads properly. If this is not done, then MPFR's cache variables are shared between threads, leading to a crash (see Section 4.7, Memory Handling, in the MPFR documentation).

Technically, this is not a bug. But please do this, since it will save the next poor soul many frustrating hours debugging their code...
