Summary: Linker problem on HP-UX 11.00

Initial Comment:
I use the following command to run the configure 
script:

CC=cc \
OPT="+DAportable" \
INSTALL="./install-sh -c" \
./configure --with-threads --without-gcc \
--with-cxx=/opt/aCC/bin/aCC --without-libd \
--with-cycle-gc --prefix=/opt/python \
--exec-prefix=/opt/python

In the Makefile I get the following lines:

CC=		cc -Ae
CXX=		/opt/aCC/bin/aCC
LINKCC=		$(PURIFY) $(CC)

The build then fails with:

/usr/ccs/bin/ld: Unsatisfied symbols:
   _main (first referenced in Modules/ccpython.o) 
(code)
*** Error exit code 1

If I edit the Makefile, thus:

CC=		cc -Ae
CXX=		/opt/aCC/bin/aCC
LINKCC=		$(PURIFY) $(CXX)

The builds succeeds.

LINKCC already was set to CXX before (configure.in 1.113);
that was undone later (1.198). Unfortunately, none of these
checkins indicate why they have been done; I recall that
people where complaining that python requires libstdc++ on
Linux.

I've now designed a test that checks whether CXX must be
used to link if main() was compiled with CXX. I cannot test
it on a system that has this property, so I'll attach it to
this report.

When patching configure fails for you, please re-run
autoconf. If you don't have autoconf, please fix the two
line numbers in the patch to match your configure; the patch
should apply then.

Martin, do you understand the logic in configre.in enough to
suggest a patch? If not, please unassign it.
