Description:
        Bash builtins will not compile with g++.

Repeat-By:
        Write a bash builtin and attempt to compile it with g++.

Fix:
        The problem occurs because the __P macro defined in
include/stdc.h
        is overridden by /usr/include/sys/cdefs.h which adds a throw()
to
        the argument replacement.  This would be fine except that
general.h
        in the bash code uses the __P macro as part of a typedef.

        My cheesy hack for my case was to redefine the __P macro back
        to what after it is in the bash code the inclusion of the
        system headers.
