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.
