DJGPP executables appear to Windows as a 16-bit DOS executable.  Windows 
cannot tell if a 16-bit DOS executable supports long file names or only 
short file names - so it always assumes the lowest capabilities and sends 
the short file name.

Create a file with a .cmd extension (similar to a .bat file, but known to 
know about advanced file names).  For example, testecho.cmd contains:
c:\djgpp\bin\echo %1
pause

When you drag onto the .cmd file you should get the long file name in the 
argument list, which will then be passed as the long name to the DJGPP 
executable.
