I can't reproduce the problem on my system.  Can you recreate the bug?  Then
attach libcpp/Makefile, libcpp/config.log, and libcpp/config.cache?

Thanks

Tail end of build log

Note the portion of the log that read

checking whether gcc supports -pedantic -Wno-long-long... yes
test: no: unexpected operator
checking dependency style of g++... gcc3
checking whether time.h and sys/time.h may both be included... yes
checking whether string.h and strings.h may both be included... yes
test: no: unexpected operator
checking how to run the C++ preprocessor... g++ -E

Looks like the configure is broken.

One thing I can see from the log is that configure is acting as if
ENABLE_BUILD_WITH_CXX is enabled.  Can you try the following patch on
libcpp/configure, and see if that fixes the problem?

This patch appears to fix the problem.  At least, bootstrap has made it
past the initial build of libcpp.  I don't know if this is the correct
fix in that I know very little about autoconf.

Does the patch also fix the hpux failure?

configure.ac needs to be changed and configure rebuilt.

I posted the fix yesterday.  I'm write-after-approval, and I thought I needed
to wait for someone to OK the patch.

The actual patch makes the change to configure.ac and regenerates configure
from there.

Probably could have been applied as obvious.

Given that your subject line includes freebsd8.0.  I doubt anyone
will jump up and review your patch unless you specifically ping the
person who approved your original patch.

I also doubt write-after-approval applies in a situation where
your previous commit has completely broken the ability for
more than one OS to bootstrap.
