I have PHCO_20721 installed, but not PHCO_26158.  And I just wasted
about a half hour of my life trying to *find* it.  It seems that HP
has not only stopped writing patches for HP-UX 10.20 (which is fine,
understandable) but has also removed them all from their machines.
I haven't tried the Bit Torrent networks yet.... :-/

My locale is set to 'en_US.iso88591'.

Here's the exact sequence (without gawk available):

Yes, I'm using GNU sed and GNU make already.  The issues with HP-UX 10.20's
sed and GCC are well known, but this is the first time I've run into an
awk issue, so I figured it should be documented.

I have GNU pth installed in /usr/local, and (according to gcc/config.log)
it's finding pthread.h.  This is probably confusing it.

Looks like it found the pthread.h header in /usr/local/include but didn't
link with the libpthread.{a,la,sl*} in /usr/local/lib.

All right.  Thanks for the information.
