I uploaded a zip of both the source and the executables to
http://www.lustbader.net/getcmdlinetest/ (it's a modification of the "Hello
World" app generated by MSVC automatically).  Run MainProc.exe and choose
Help, About, which will run the other process (make sure to run MainProc.exe
from the directory it's in).  Both windows should display the commandline they
were started with.  In Windows, you should see one window display MainProc.exe
and the other display SubProc.exe.  With Wine, the first window will display
MainProc.exe and the other won't display anything.  If you run SubProc.exe by
itself, in either Wine or Windows, the command line is displayed correctly.

Thanks for the test program. This should fix it:
