Every windows application will need msvcrt.dll to run. This is something =
like
the libc.a and other libraries in Linux.
I have used objdump to see which dll's need my cross compiler and which d=
ll's
are needed by a native program build by Mircosoft.
There is a difference:
The cross build program needs msvcrt.dll.
The native program needs MSVCRT.dll.
On Windows this doesn't matter, but maybe wine has problems with the lowe=
r case
version. I couldn't believe it, but it can be possible.

You can use:
objdump -x w1.exe > w1.dump
objdump -x w2.exe > w2.dump
diff w1.exe w2.exe | less

Then you will see the difference.

Have you tried to run w2.exe on Windows?
Does it work?

Some questions about your cross compiler:
Which sources have you used?
How did you build your cross compiler?
Which runtime version are you using?
Which version of binutils?
