Sorry, that's my fault again. I couldn't check whether the new
backtrace stuff worked on mingw, I guess that's the problem. But I
should have seen that the new code imports a posix header even on
windows.

Could you please check if this patch fixes it:
https://gist.github.com/2253215

(That disables the GCC backtraces for non-Posix systems completely.
Windows has custom backtrace code anyway.)


BTW: @Iain Could you have a look at the build instructions at
https://github.com/D-Programming-GDC/GDC/wiki ? I just changed the git
checkout commands and symlinks, but it seems that
gcc-x.x.x/gcc/libphobos can't be a symlink anymore, so this directory
needs to be copied?

Or should the repository just be checkout out into the main gcc-x.x.x/
folder? Does git somehow allow to checkout into an non-empty folder?
