This works. I had a look at changing the llvm-config.in.in but my Perl hacking
skills aren't up to getting --libnames and --libfiles to work as well as --libs.

I discovered one other thing that was causing me problems on MinGW: if I use the
msys.bat to open a terminal llvm-config inserts double slashes at the start of
any absolute path it generates (e.g. //lib/LLVMX86CodeGen.o) - this breaks g++.

If I do the same thing from a DOS prompt running bash, slashes don't get doubled
and everything works fine.

Thanks once again Óscar and Anton.
