2 oops for you

both came while under linux 2.0.0 (libc 5.3.12, new libg++, new binutils,
etc) while trying to cp sendmail to /usr/local/bin :) ginch is a
slackware 3.0.0 system, w/ everything upgraded (hopefully correctly, I'm
still finding occasional problems :( ) as required by the kernel Changes
document :)

Thanks guys, keep up the GREAT work.
