Hi again Ralf,

OK, new branch from the master here:

The first two commits are the changes already discussed.

The third commit provides a fall back value (based on the DLL on
my machine) as done for MSVC v8 and v9, and updates the live
lookup via msvcrt.CRT_ASSEMBLY_VERSION to actually check
what version that is (the current code wrongly assumes it is going
to be for MSCV v9):

Do you want a pull request for that work so far? Or can you
suggest what I should investigate next since there is at least
one more hurdle to clear before I can build it (build output below).




I now get further trying to build with mingw32 (from this branch
from master, not the numpy-1.7.0b2 files this time), an excerpt
from which this line may be note-worthy:

Cannot build msvcr library: "msvcr100d.dll" not found

This omits the failure to detect ALTAS etc which seems irrelevant.
I would guess the MismatchCAPIWarning is an unrelated issue
from working from the master branch this time.

C:\repositories\numpy>c:\python33\python setup.py build --compiler=mingw32
Converting to Python3 via 2to3...
numpy\core\setup_common.py:86: MismatchCAPIWarning: API mismatch
detected, the C API version numbers have to be updated. Current C api
version is 8, with checksum f4362353e2d72f889fda0128aa015037, but
recorded checksum for C API version 8 in codegen_dir/cversions.txt is
17321775fc884de0b1eda478cd61c74b. If functions were added in the C
API, you have to update C_API_VERSION  in numpy\core\setup_common.py.
