test program

Hi,

Quicken 2014 loads the stub ntdll from C:\Windows\System32 as file mapping and
tries to compare it with all loaded file mappings using
NtAreMappedFilesTheSame. Wine does not support comparing a mapped stub dll with
the loaded dll, so that the function returns STATUS_NOT_SAME_DEVICE every time,
causing Quicken 2014 to enter an endless loop.

Since this issue is currently blocked by bug 37487 and bug 37449, I wrote a
small C snippet which can be compiled with mingw that demonstrates the issue.
On Windows the program prints "Same file!" while on Wine it prints "Different
file!".

Regards,
Michael
