Function strstr and MinGW

[GOUJON Alexandre]

Hi everyone,

I'm still trying to improve wine cmd but I'm stuck with my patch making 
tests failing.

After some investigations, I've found that my function which replace all 
@space@ by real spaces does not always work.
So I've written a test_case (attached code).
It runs perfectly on Ubuntu (compiled with gcc) but does nothing on 
Windows (compiled with i586-mingw32msvc-gcc).
In fact, on windows, strstr fails and so never goes into the while{ } loop.

Is MinGW the culprit ?
Should I use another function ?
Any idea ?

[Why *standard* function don't even work on Windows ?]

Thanks in advance !
