llvm dev - Jan 2013 - [LLVMdev] Fails to compile w/ MinGW: sys/mman.h: No such file or directory

I am having trouble getting LLVM/Clang to compile from SVN/trunk on win32
using MinGW (4.7.1). The error is:
sys/mman.h: No such file or directory
...and it happens during compilation of:
[LLVM/Clang]\projects\compiler-rt\lib\enable_execute_stack.c
I configured everything carefully as "CMAKE_BUILD_TYPE"
"Release". I have in
the PATH (in that order):
- CMake
- MinGW
- Python 2.7.2
- ActivePerl
- Subversion 1.7.x
- GraphViz 2.3.0
All tools are found, configuration w/ Cmake succeeds hence that error. It
used to work like that when I compiled earlier, but that's roughly 4 month
ago. :-/

What can I do?

BTW: I think I posted this to the wrong mailing list in the first place, so
I repeat here (sorry for that):

Just don't build compiler-rt. And yes, instructions should be modified
to outline that compiler-rt is optional step.

stupid
now. Thanks for the help!Just out of curiosity: Why it used to work earlier?
Is it included now by default or something like that? I don't think I
changed the CMake config too much in tat direction - but I'll check... ;-)

Why is the header using sys/mman.h, isnt it supposed to be using 
llvm/Support include files such as MemoryBuffer ?

Thanks
