one of those annoying little things

[Dennis Clarke <dclarke@blastwave.org>]

Dear ALL :

     Not sure who else have been doing bootstraps on machines wherein the
common sense thing to do is protect the source tree. What I mean is that
I extract the gcc 12.2.0 tarball of joy as the root user. Then inside
that directory structure I crack out the gmp/mpfr/mpc goodness and even
apply the correct patch for mpfr[1].

     So anyways, funny thing happens when I try to build out of tree :

Turns out, wild, but that directory for the mpfr doc stuff has files
that no user has rights to other than root. That has to be a bug right?
Could be the mpfr guys but hey this seems weird.

So I did a chgrp "foo" on that whole dir and also allowed common dirt
humans to read and write the mpfr.info file. That seems to allow
bootstrap to continue for those dirty users. Not sure if anyone else
sees this as a bug or just a feature.
