Did so, and learned something new (already knew about the a.out a.exe pair). 
Thanks !

I also have done some digging and found:

= "This has also one side effect. If you call gcc like
=
= gcc -o foo foo.o
=
= the file foo (without the exe suffix) is created but it IS a
= '.exe' file. That means to prevent misunderstandings call gcc
= at any time like
=
= gcc -o foo.exe foo.o "

And maybe that is what I recalled. The quoted text is from a "readme.djg" about the port of binutils 2.8.1 and is about what happens if one changes the 'specs' file as the author Robert Hoehne suggests.

When I first got djgpp I had to read through many documents like this, in the hope to find some clue somewhere of how to get it to work. These documents are written for experienced and advanced djgpp users. Their impact on beginners is rather unpredictable :-)

Still think it's a good habit to use a *.exe name with the -o option. 
But the correct reason should be: to avoid creating unwanted COFF files

And still warmly recommends the -Wall option. Especially to newcomers arriving from the sheltered Java environment.
