Historical note: I think the 'main.exe' behaviour got lost when I ported
the old Perl driver into Haskell. Sorry about that!
Comparison note: cygwin gcc uses 'a.exe' as the default linker output.
Microsoft's toolchain calls it 'foo.exe' if the first object file is
called 'foo.obj'. Based on this, I'd say 'main.exe' is reasonable.
Cheers,
Simon
