And at the end, I did:

ln -s /usr/local/mingw/bin/* /usr/local/bin/

And I checked if echo $PATH had /usr/local/bin in it:

echo $PATH
/opt/local/bin:/opt/local/sbin:/Users/maelv/.opam/system/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/texbin:.:.

Thanks a lot! I compiled all of this staff with newest versions of packages (except gcc ). And it works. Only one remark: to compile last lib winpthreads I added PATH before run configure to prevent include errors.

PATH=/usr/local/mingw/bin/:$PATH \
 ../configure --host=i686-w64-mingw32 --prefix=$PREFIX/i686-w64-mingw32

Also I was looking for possibility to use std::thread. I found the solution. If you prefer to use this instead of win32 you need to change --enable-threads=win32 to --enable-threads=posix and recompile gcc-core, mingw, gcc all.

Great script! I played with maelvalals version to make a macports version, learning a lot of new things about bash in the process. :) (the macports port of mingw is quite a bit out of date and doesn't have a 64 bit version) Also updated it to gcc-4.9.3,MinGW-4.0.4 and Binutils-2.25.1, because why not? Also fixed a few typos with the zip check.
There is some sort of bug with macports gmp version so I had to make it use the the built-in apple one.

I've made a few changes for yosemite. Those changes I could build successful.

These scripts specifically target an older version of ISL. To install it brew install isl011 isl012 cloog018

I am working on a homebrew version of this script.
EDIT: I just noticed that cosmo0920 (https://github.com/cosmo0920/homebrew-mingw_w64) has already begun to work on a brew version of this script.
