unistd.h in nptl/unwind.c

With today's cvs glibc and nptl 0.39, I find that I have to #include <unistd.h> in nptl/unwind.c
to avoid this error:

make[1]: Leaving directory `/usr/src/libc-work'
make: *** [all] Error 2

(there were also some 'inlining failed' errors, but I can't find them right now)

The includes map that is attached shows that no (non kernel) unistd.h is imported, so
STDERR_FILENO goes undeclared.

The error did not occur before I recently upgraded my system gcc to the 3.3 release.  Previously I
was using a 3.3 cvs from april.  Is it possible that some changes to the fixedincludes in gcc have
been made, resulting in unistd.h no longer being implicitly included in nptl/unwind.c ?

Should I be using gcc 3.4 instead?

Thanks
