work around compiler bug on CX/UX (perl5.004_01)
This patch provides a work-around for a compiler bug on CX/UX systems (which
shows up as a failure in the 'w' format of pack). The
CXUX_BROKEN_CONSTANT_CONVERT ifdef flag is added to the hints/cxux.sh
compiler and pp.c is modified to avoid a compile time constant conversion
which fails based on that ifdef.
While I was in the hints file, I also added the magical
-Qtarget=M88110compat compiler option which makes it build code that will
run on both 88110 and 88100 CX/UX machines interchangably.
This patch was generated from a brand new copy of perl5.004_01, so I'm
confident there are no extraneous changes that slipped in. I even built
and tested and it passed all tests.
(I decided to go with option #3 in my previous mail about how to do the patch).
If its too late for 5.004_02, I wouldn't worry - it isn't very critical.
