Unfortunately, there seems to be a problem with the machine in the compile farm
that I use for gcc development, and I'm not able to finish a
bootstrap&regression test. I always get:

couldn't create output pipe for command: too many open files

even for a pristine copy of GCC. This didn't happen a few days ago. I didn't
have time yet to investigate what is wrong. If someone can bootstrap&regtest
the patch for me, I will commit it with proper changelog and send it to
gcc-patches.

(Of course, hints on how to fix the above problem are more than welcome. This
issue prevents me from doing any GCC development right now).
