I just built and installed 1.0 on hpux hppa with gcc-2.5.8. Nice job!
Just one minor point though. Since on hppa (and on linux) -g forces
static linking I recommend that the default CFLAGS and LDFLAGS do not
use -g. Otherwise the binary is MUCH larger. And I seriously doubt
very many people using octave would want to debug it. If they did
they already know all about this anyway.
