[conflict between DJ's 'echo.exe' and the one from GNU shellutils]

Why not put 'echo.exe > s-objlist'? As long as 'echo.exe' is a DJGPP, the
system() implementation of redirection should be able to handle that,
right? 

Anyway, that name conflict ought to be solved for real. IMHO, we simply
should not have two programs in the distribution zips with the same name.
For DJ's 'merge' and 'split', this was already addressed (they got a 'dj'
name prefix), so I'd say DJ's 'echo.exe' should also be renamed to
'djecho.exe', vor V2.02, and the gcc makefiles changed accordingly.

Comments, DJ?

I'd suggest rewriting 'mklibgcc' to write out a sub-makefile, that will
then be used by the toplevel-make via '$(MAKE) -f libgcc.mak'.
