I have a Windows console application that I build in both 32-bit and 64-bit
versions. They both have the same name (fsr.exe).

The 32-bit version runs from a CYGWIN bash shell console window on a 32-bit PC
and a 64-bit PC. The 64-bit version runs from a Cygwin bash shell console window
only on a 64-bit PC.

If a user mistakenly runs the 64-bit version from a CYGWIN bash shell console
window on a 32-bit Windows PC he gets this message:

bash: ./fsr.exe: Permission denied

That's not very revealing.

On the other hand, if he launches the same command from a CMD console window on
the same 32-bit Windows PC, he gets this back:

This version of fsr.exe is not compatible with the version of Windows you're
running. Check your computer's system information to see whether you need a x86
(32-bit) or x64 (64-bit) version of the program, and then contact the software
publisher.

The second result is closer to what I was hoping for.

So my question is this: Why isn't CYGWIN responding with the more helpful error
message and is there anything I can do to make it respond that way instead?
