Do you mean stale typedef in gcc's private copy under
  PREFIX/lib/gccXY/gcc/*/*/include-fixed/sys/types.h ?

You can fix the file manually instead of wasting cpu cycles.

  $ gcc46 foo.c
  In file included from /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/4.6.1/include-fixed/unistd.h:46:0,
                   from foo.c:1:
  /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/4.6.1/include-fixed/sys/types.h:111:1: error: unknown type name '__cpumask_t'
  Exit 1

  $ sed -n 111p /usr/local/lib/gcc46/gcc/x86_64-portbld-freebsd9.0/4.6.1/include-fixed/sys/types.h
  typedef __cpumask_t     cpumask_t;
