- Reply-to: sje at cup dot hp dot com
While working on the IA64 HP-UX port of GCC we have found it useful to
have a version that runs on PA and generates code for IA64. To this end
I added code in libstdc++-v3 configure.in to support this cross
compiler. Since it had a lot of duplication with the linux cross
compiling support, which in turn duplicated a lot of the generic cross
compling support I merged the common stuff instead of having 3 copies of
it and only put what was actually different between the platforms in a
case statement. Thus configure.in is 5 lines shorter then it was
instead of 50+ lines longer.
I would like this reviewed and checked in if it is OK, I tested it by
building an HPPA to IA64 HP-UX cross compiler and running the g++
testsuite.

* libstdc++-v3/configure.in: Add support for hpux cross compiles,
combine common linux/hpux/generic cross compile support to reduce
redundent lines.
* libstdc++-v3/configure: Regenerate.
