description     C library for multiple-precision floating-point computations
long_description \
    MPFR is a portable C library for arbitrary-precision binary \
    floating-point computation with correct rounding, based on the GMP \
    multiple-precision library. The computation is both efficient and \
    has a well-defined semantics. It copies the good ideas from the \
    ANSI/IEEE-754 standard for fixed-precision floating-point arithmetic.

# Due to radr://10291355 (llvm.org PR11111), the new tls support enabled in clang with Xcode 4.2
# miscompiles mpfr. While this was fixed in Xcode 4.2.1, as the ttls support was never used prior to
# Xcode 4.2, the generic fix is to pass --disable-thread-safe to configure.
