MinGW GCC 4.8 with GDC

[Daniel Green]

I got GDC working with GCC 4.8 on MinGW.  You can find it at

https://bitbucket.org/goshawk/gdc/downloads/GCC-4.8-MinGW-GDC-.7z

A couple of notable things.  It's ALPHA quality.  If it works, you're 
lucky.  You'll find regressions.  The patches required to fix some of 
the past bugs haven't been transferred yet.

It also fails the following DMD testsuite tests.

test36 test4 test42 testdstress testmodule testsafe

Currently, there is no build script.  You'll need to recompile all 
dependencies manually.

It's standalone.  It is no longer required to have TDM or any other 
variant of MinGW installed prior.  This increases the size of the 
package.  Also, there's no optimization flags being used.  So everything 
is bigger as well.

It's only 32-bit.  64-bit forthcoming.

For GDC licensing see gpl.txt.

Installation:

This is a self contained MinGW release.  Extract GDC folder to directory 
of choice.


Building:



** Deviating from the versions specified may cause intended 
consequences. ie: Build failures, random crashes **

Ensure fstab as the following entry.  Substitute C: for drive of 
choice(Should work)

C:/crossdev /crossdev

Download the following packages:

binutils-2.23.1.tar.gz
cloog-0.18.0.tar.gz
gcc-4.8-20130303.tar.bz2
gmp-4.3.2.tar.bz2
isl-0.11.1.tar.bz2
mingwrt-3.20-mingw32-src.tar.gz
mpc-1.0.1.tar.gz
mpfr-3.1.1.tar.bz2
w32api-3.17-2-mingw32-src.tar.lzma

Clone GDC.  The checkout version is what I have the patches will 
properly compile.

git clone https://github.com/D-Programming-GDC/GDC.git
git checkout 166e02c2e99c3f6926513bb617593f24b7f4456f

Extract the download files to a directory called src.

Build in this order.  All commands are assumed ran from a directory called
build within the respective source directory
