Re: followup to segfault/builtin_expect

[David Ford]

Ok, the __builtin_expect is fixed, I replaced my 'ld' which I now suspect was
corrupted.  config.h built correctly with this undefined.  I also took your
advice and followed FAQ 2.2 to the letter with the following:

CFLAGS="-pipe" ./configure --prefix=/usr --enable-add-ons, and no configparms
file.

It started off well bug again segfaulted in sunrpc.
