I configure with --disable-libstdcxx-pch which also reduces build-time.
If I understand correctly the issue, to test without PCHs I used to 
configure / test / etc normally and then by-hand remove the generated 
PCHs and run make check inside libstdc++-v3/testsuite (*not* inside 
libstdc++-v3) in case of need. It's an HACK, which exploits sort of a 
bug: in that case make check doesn't lead to the automatic regeneration 
of the PCHs.

I just committed this patch as trivial.

I must have run tests without rebuilding pre-compiled headers. I'll have 
to find out how to build tests without pre-compiled headers to avoid it 
in the future.
