GDC should build for MINGW and MINGW64 targets, however not much testing has been done.

Building

The following patches are required for binutils / gcc to fix TLS support:

• https://github.com/venix1/MinGW-GDC/blob/master/patches/mingw-tls-binutils-2.23.1.patch
• https://github.com/venix1/MinGW-GDC/blob/master/patches/mingw-tls-gcc-4.8.patch

This patch is required to fix a bug in GCC buildscripts:

• https://github.com/venix1/MinGW-GDC/blob/master/patches/gcc/0001-Remove-fPIC-for-MinGW.patch

SEH

GCC supports SEH for Windows 64 bit targets, but GDC has not been tested with SEH enabled. It also does not compile right now because no SEH personality routine has been written yet (__gdc_personality_seh0).

Configure gcc with --enable-sjlj-exceptions to use SJLJ execptions for win64 targets. DWARF exceptions are untested.
