Rust low-level bindings for GMP and MPFR

The gmp-mpfr-sys crate provides Rust low-level bindings for the GNU Multiple Precision Arithmetic Library (GMP) and the GNU MPFR Library, a library for multiple-precision floating-point computations. The source of the two libraries is included in the package.

Building on GNU/Linux

To build on GNU/Linux, simply make sure you have diffutils, gcc and make installed on your system. For example on Fedora:

```sh

sudo dnf install diffutils gcc make

```

Building on macOS

To build on macOS, you need the command-line developer tools. An easy way to install them is to start building the crate using cargo build. If the tools are not installed yet, a popup should appear which should help you install them.

Building on Windows

You can build on Windows with the Rust GNU toolchain and an up-to-date MSYS2 installation. To install MSYS2, you can do the following:

Install MSYS2 using the installer.
Launch the MSYS2 MinGW 64-bit terminal from the start menu.
Install the required tools.

```sh $ pacman -S pacman-mirrors

$ pacman -S diffutils make mingw-w64-x86_64-gcc ```

Then, to build a crate with a dependency on this crate:

Launch the MSYS MinGW 64-bit terminal from the start menu.
Change to the crate directory. Note that building the GMP and MPFR libraries in MinGW with absolute paths does not work very well, so relative paths are used. If your crate is inside C:\mingw and the .cargo directory is outside C:\mingw, this will not work. Please move your crate to the same side of C:\mingw as .cargo.
Run cargo build.
