3d7622d0f5 We need to include config.h to get the proper setting to LLVM_MULTITHREADED.

ed1c0ffe0b Add a portable strerror*() wrapper, llvm::sys::StrError(). This includes the 
Windows variant, strerror_s, but I couldn't test that.

I'll update configure and config.h.in in a subsequent patch.

Can someone with access to a Win32 machine test/fix this?

c9f8e8ebab Improve the Win32 reader-writer lock implementation by making it just a normal 
lock.  This is obviously bad, but at least it's threadsafe!  If you know how
to improve this in a pre-Vista friendly well, patches welcome!

070c42f311 glibc has two versions of strerror_r, a standards compliant one and a GNU 
specific one. The GNU one is chosen when _GNU_SOURCE is defined. g++ always
defines _GNU_SOURCE on linux platforms because glibc's headers won't compile
in C++ mode without it. The GNU strerror_r doesn't always modify the buffer
which causes empty error messages on linux.

This patch changes MakeErrMsg to use the return value of strerror_r to get
the string instead of assuming the buffer will be modified, on GLIBC.
