Re: mpich C++ transition status

Following up on the issues from my previous note that still exist.  Sorry
that I hadn't given this attention sooner; I've been a bit buried
preparing for vacation.

I've filed a bug against r-base for this.  I'm going to file it at
severity: important since I don't want the bug itself to block migration
if hppa gets built properly, but if that's not correct and it should be
upgraded, please feel free to either do so or ask me to do so.

I've now seen this problem elsewhere, and it's a problem with binutils on
powerpc.  krb5 appears to also be affected.  See Bug#329686 for more
details.  Rebuilding the affected library from source should fix the

I'm not sure the right approach to take here.  A new libf2c2 build on
powerpc with the current binutils will fix the problem; should I file a
bug against libf2c2 asking for a new sourceful upload to unstable, or is
this the place for a porter binary NMU?  I never entirely understood how
those are supposed to work and when they are appropriate.

Bug filed.
