I ran this again, this time in the WinPE command prompt, with the following results.

C:\hxtest\win32>test.exe foo bar >test.txt

C:\hxtest\win32>type test.txt
COMSPEC=X:\i386\system32\cmd.exe
argc=3
argv[0]=C:\hxtest\win32\test.exe
argv[1]=foo
argv[2]=bar

C:\hxtest\win32>test2.exe test.exe foo bar ">test2.txt"

C:\hxtest\win32>type test2.txt
COMSPEC=X:\i386\system32\cmd.exe
argc=3
argv[0]=C:\hxtest\win32\test.exe
argv[1]=foo
argv[2]=bar

Interesting that argc=3 when running test2.exe on Windows, but argc=5 when running test2.exe on HXRT. This leads me to believe that the blame rests somewhere other than the OpenWatcom compiler.
