[cfe-dev] MinGW problem with GSL

[Ruben Van Boxem]

Hi,

Clang seems to have a problem with some assembler files when building
GSL (configured with --host=x86_64-w64-mingw32 CC="clang -v"):

GCC does not have this problem. I can't discern any notable difference
in config.log. Could it be something wrt passing options down to the
GNU tools?
