In DJGPP, sh.exe is a ``symlink'' to bash.exe.  If you look at
bin/sh.exe on your system, you will see that it's only 2KB long.
That's simply a stub loader which was configured to load the code from
bash.exe.

So you could say "SHELL = /bin/bash" as well, it's just that /bin/sh
is more portable, since some Unix systems don't have Bash.

For more about the "SHELL = /bin/sh" magic, read the file README.dos
in the Make distribution (mak3791b.zip).
