No problem.  Please post such questions to the list in future
though, where they may serve future users.

Actually, no there is no straight forward way to do it in m4 right
now.  It *is* a good idea though, and I will add it to M4-2.0.

In the mean while, I would write:

$ cat aoeu.m4
#!/bin/sh

exec m4 <<'EOF'
define(`foo', ```foo' here'')dnl
foo
EOF
exit 1
$ ./aoeu.m4
`foo' here

HTH,
        Gary.
