Thanks a lot for this. It helped a lot.

I got your binutils 2.20, installed (into a clean .wine environment),
and used the original numpy code
from the maintenance/1.7.x, it still fails with the "ValueError:
Symbol table not found" exception
due to this problem:

Z:\home\ondrej>objdump -t
objdump: C:\windows\winsxs\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4148_none_deadbeef\msvcr90.dll:
File format not recognized

My binutils are correct now:

Z:\home\ondrej>objdump --version
GNU objdump (GNU Binutils) 2.20

So now I know that the problem is not there, and so it must be in my
msvcr90.dll library somehow. I will keep digging.
