For native Windows programs, that's true, of course.  But DJGPP
programs are DOS executables, as far as Windows is concerned, and DOS
executables are barred from issuing the Win32 API calls for file
access.  So DJGPP programs cannot access the long file names except
through a special API avail;able to DOS programs (a bunch of functions
of Int 21h).  That API is not supported by NT versions before 5
(i.e. before W2K).  Windows 9X always had it included.  The DJGPP
library detects this API at startup and automatically switches all
library functions to use that API, thereby proividing a transparent
support for long file names.
