	* sysdeps/unix/sysv/linux/s390/s390-32/sys/ucontext.h: Revert the
	change of the gregset_t type.
	* sysdeps/unix/sysv/linux/s390/s390-64/sys/ucontext.h: Likewise.

2001-08-20  kaz Kojima  <kkojima@rr.iij4u.or.jp>

	* sysdeps/unix/sysv/linux/sh/sysdep.S: Align errno.

	* posix/regex.c (truncate_wchar): Use wcrtomb not wctomb.
