Oh, does this url still work now? I had to change it in llvm-mingw a while 
back, 
https://github.com/mstorsjo/llvm-mingw/commit/ad3d710c9a0fe40193b01c4a87fb0cde7fdf9718#diff-61ff93e7b0a019a6b2791677ea7c6770, 
as the old SVN url didn't seem to work at the time. But maybe it only was 
temporary - keeping the old SVN intact at the old url would indeed be the 
most sensible thing to do.

Does this work with clang/llvm-mingw as well? When I tested building 
libssp using the normal automake build system (in the subdir in a full gcc 
checkout, iirc) its configure script failed due to wanting to test some 
obscure flags that clang didn't implement at the time - that's why I've 
bundled a small handwritten makefile instead in llvm-mingw. Or maybe it 
was just due to it not working standalone in a subdir?
