     We could do something like
             if test -z "$PPID"; then
                 exit 77             # Make automake ignore this test
     to cater to systems that don't have it.

That would be one option.
     But it's not a bashism.  This is what SUSv3 says:

Well it's not recognised by the /bin/sh which ships with Solaris9.

One construct which seems to work both on solaris and on GNU/Linux is
"ps -o ppid -p $$ | tail -1"  but I don't know what BSD and all the
other OSes might think of that.
