Re: [ft] freetype2 and Win64

[NightStrike]

Yes, unfortunately, our build slaves for that platform are down.  The
machine kept over heating :)

You may find it much easier to use this makefile:

http://mingw-w64.svn.sourceforge.net/viewvc/mingw-w64/experimental/buildsystem/makebuildroot.mk?view=markup

execute it like this:

make -f makebuildrook.mk

It will download the sources and build an entire toolchain for you.
