As of recent with gcc 4.5.0, to use the CLOOG_PPL_BACKEND, --with-cloog and
--with-ppl must be specified in the command line, making this more notable.

I imagine this applies to any target, not just win64 targets.  I can't change
that setting, though.

I am quite sure it applies to any target, but I am unable to test any target.
Feel free to post verifications of other targets. I should have listed the
other ones I know it applies to - like I did for build - and updated that.

This bug needs to be confirmed.

[Bug bootstrap/40516] --without-mpc, --without-ppl, --without-cloog does the same thing. No turning off mpc via configure.

I have now, in an attempt at a testcase, have found this bug to have further
implications. Trying to turn off mpc, ppl, and/or cloog has the same behavior,
i.e. --without-mpc causes:

gmpinc: '-I/no/include'
gmplibs: '-L/no/lib -lmpc -lmpfr -lgmp'

This is more serious now as mpc cannot be turned off without manual hacking. I
am surprized this has not yet been confirmed. I can also now say that target
x86_64-linux-unknown-gnu produces the same problem. It is safe to say it is
fairly target indescriminate.

How come this is still sitting unconfirmed? This is something that involves
Linux et. al. Using --without-cloog, ppl, or mpc doesn't work right as per
previous post, so it is more than just cosmetic. 

I don't really care personally, just trying to help gcc.

Presumably, because GCC devs haven't had time to look at this in detail and it
is not a priority compared to other issues. Note that at this moment there are
1288 unconfirmed bugs.

Thanks, any help is greatly appreciated.

> Is it supported to build GCC without MPC?

NO.  GCC requires mpc to build.

Also cloog/ppl support has been removed and replaced with ISL.

Toplevel configure.ac has now:
# Treat --without-isl as a request to disable
# GRAPHITE support and skip all following checks.

So I am going to assume this was fixed for ISL and MPC needs to be there and
CLOOG and PPL support was removed.

So closing as works for me.
