config.guess reports that my system is an hppa2.0-hp-hpux10.20 machine. However, I would like to build gcc using hppa1.1-hp-hpux10.20, which I believe is supported. The configure script's documentation says that the host and target systems will default to the build system unless otherwise specified.

Gcc/config.gcc seems to have an entry for hppa1.1-hp-hpux10.20 (line 970, 'hppa[12]*-*-hpux10*' is a case that matches), so presumably it should configure itself correctly.

I guess this is worth a shot regardless, so I'll try it. Thanks! I'll let you know if it works.
