Created an attachment (id=6059)

patch for the issues listed in the report

When compiling LLVM with MinGW-w64, several easy to fix/workaround issues
popped up:

1. _WIN32_WINNT redefined
2. lib/support/Windows/DynamicLibrary.inc: bad ifdef for mingw-w64 which needs
the function ifdef'ed out
3. explicit symbol declaration for functions not meant to be present on win64
MinGW platforms.
4. tblgen.exe crashes on CellSPU *.inc files

I have attached a patch for these issues (except 3). I would be much obliged if
applied to trunk.

I do not have a clue about number 4, and already opened a bug report about this
here: http://llvm.org/bugs/show_bug.cgi?id=8850
Disabling the target in question lets the build continue and finish happily.

I will update the bug report with "make check" results.
