No. I simply use '../configure ; gmake -j6 bootstrap'.
This has worked for years.  I'm currently using GNU
make 4.3. If MAKE is not being set to gmake, then I
would expect bootstrap to fail.=20

I plan to run gmake with debugging output, and need to
check gmake.info to see how to dump the environment
information.

I suppose I'll start using the 'MAKE=3Dgmake ..' form or some variation
as I use tcsh.=
