well, just to make sure they all still work... If there are problems =

Ah yes, I already found one issue when building head on 9-STABLE:

In file included from contrib/llvm/lib/Support/Signals.cpp:30:
contrib/llvm/lib/Support/Unix/Signals.inc:22:11: fatal error: =
'execinfo.h' file not found
# include <execinfo.h>         // For backtrace().
          ^

This is of course a detection from autoconf which finds execinfo.h on
-current.  So I will need to make that __FreeBSD_version dependent.
