I don't understand: is this *new*? Is it related to the recent commits for
libstdc++/1773? (note, some don't appear in the trail because Rainer typoed
libstdc++ as libstdc++-v3 in the ChangeLog entry header). Maybe HPUX needs some
massaging similarly to Solaris?!?

It is new and probably caused by the commit for libstdc++/1773.
I'm investigating.

It looks like this is caused by r177877, where libcpp was changed to
set __cplusplus to 199711L instead of 1.  I think this is interacting badly
with the HP system headers somehow.

The HP headers have checks for '__cplusplus < 199707L' and those checks
are going to be different now.

Somebody knowledgeable of HPUX should see what needs to be done for that OS. I
suppose the changes figured out by Rainer & Marc for Solaris, a mix of
fixincludes + mangling changes via target hook + a bit of library work, should
be a good starting point for HPUX too:

I am testing an inclhack.def header file fixup for abs.  I am not sure if any
of the other header files checks on __cplusplus will be a problem but fixing
the abs problem should get us bootstrapping again.

Great!  Please install if change tests successfully.

Looks similar to:
https://issues.apache.org/jira/browse/STDCXX-244
so fixinclude seems right.

Out of curiosity, what else depends on the value of __cplusplus in those
headers?

I think all I need to do is expand the existing hpux11_abs fixinclude rule
from 'ia64-hp-hpux11*' to '*-hp-hpux11*'  I am currently testing this.

The other checks for '__cplusplus < 199707L' in the header files don't
like like they should cause problems.  They set NULL to 0 (old) vs. 0L (new),
add a define for _WCHAR_T, and set some macros to specify that the long long
type is always available.  I think all those things should be OK.

I am testing my patch but had some system problems over night so I don't have a
complete bootstrap and test yet.
