I can see how this mistake was made (since I made it also): the binary
file on your server (cs.nyu.edu/pub/gnat) lists the file with "586" in
the file name.

I thought that it wouldn't run on my 486 and have continued to use
the DOS version (with no tasking).

Maybe someone (GNAT developers anyone?, anyone?) could comment on the
differences between GNAT and gcc between DOS and NT.  I know that
Windows 3.1 uses the "new executable file" format for programs rather
than what is used in DOS (I don't know what Win32 programs use).  I
also suspect that GNAT under dos is generating 32-bit
executables (some sort of 32-bit extender maybe?).

Anywhere where a curious programmer can find answers to the above
questions?

So may Microsoft Operating systems,
So little time,
