No idea whether it is related; but I'd appreciate if you filed a bug

Done. It's libstdc++/41220, definitely a regression. Thanks in advance
for your help!

Confirmed. You can work around it with 'rm include/stamp-host' before running 'make' again. Patch below.

This issue existed before the autotools upgrade (verified with r151011).
I assume the non-regeneration of these headers is a long-standing issue,
only exposed through r150672 which introduced<extc++>  inclusion into
the testsuite:

2009-08-11 Benjamin Kosnik<bkoz@redhat.com>

         * include/precompiled/extc++.h: Don't include TR1 if C++0x.
[...]
         * testsuite/17_intro/headers/c++1998/all.cc: Use extc++.h include.

A 'git grep extc++ fbf4148e0248e4dfab55109dde400e848f76e43b^ -- testsuite'
shows that there were no uses of this header in the testsuite before that
commit.

OK to apply?

Yes, thanks!


Paolo
