All the information I have on this was derived from the
Win32 SDK documentation that came with MSVC 4.0 followed
by experimentation.  I do not have the answers.  However, I
probably made a typo in the message I sent out:  the information
was for long command lines, not long file names as above.

My interest in this is that I am considering using gnu make
instead of MSVC's nmake, so I went looking for the mechanism
nmake uses to pass long command lines to cl and other 
MSVC tools.

I am not aware of any switches to enable or disable long command
line support, although clearly it is limited by the amount of
environment space available.
