IMHO, the problem is not about the code built with gcc but WinNt itself.
Win9x/2k/Me allow a program to access files in the LFN format, even if it
is a 16 bit executable, through an API. With WinNt you don't have this
gadget. Andrew Crabtree and Wojciech Galazka wrote an utility
program:lfnload to implement this API for WinNt. I think you may try it.
Pls check http://www.cybertrails.com/~fys/longfile.htm. and Simtel along
with other djgpp stuff.
