Do we really want to force AC_CANONICAL_HOST here, as well as blindly
always enabling the define for all HP setups?  It seems like this would be
better written as a compile-time test that sees whether mbstate_t is
visible first without, then with -D_XOPEN_SOURCE=500 added to CFLAGS, in
case HP (or gcc fixincludes) fixes the problem, or in case someone else
has a similar issue.
