Re: Patch to config.guess (2002-07-03) to detect 64bit HPUX compiler

Ben,

I couldn't find the code you were referring to but here is a cut of that
patch.  It still requires
a C compiler but does not create temporary files.  It has not been tested
with aCC but has
been with gcc, cc and cc +DA2.0W.

      echo ${HP_ARCH}-hp-hpux${HPUX_REV}
      exit 0 ;;
      ia64:HP-UX:*:*)

I am really resisting patches that use the nasty inline shell fragment
`$set_cc_for_build'.  It is a constant source of frustrations.  I am
loathe to use it more -- is there any way you can use other system
facilities to discover the same information?

If you look at some of the Linux detection code, there are some nice
tricks there that employ pipelines through cpp, if that's what you
need.
