We could do something like
if test -z "$PPID"; then
exit 77 # Make automake ignore this test
fi
to cater to systems that don't have it.
But it's not a bashism. This is what SUSv3 says:
PPID
Set by the shell to the decimal process ID of the process
that invoked this shell. In a subshell (see Shell Execution
Environment), PPID shall be set to the same value as that of
the parent of the current shell. For example, echo $ PPID and
( echo $ PPID ) would produce the same value. This volume of
IEEE Std 1003.1-2001 specifies the effects of the variable
only for systems supporting the User Portability Utilities
option.
