+ * sysdeps/mach/hurd/sigwait.c (__sigwait): When returning immediately,
+ check only (SS->pending & MASK) for the signal to return.
+ From Jeroen Dekkers <jeroen@dekkers.cx>.

2001-12-22 Roland McGrath <roland@frob.com>
+ * iconv/skeleton.c [!RESET_INPUT_BUFFER && !SAVE_RESET_STATE]:
+ Use preprocessor #if conditionals instead of `if' to avoid
+ warnings about divide by zero in dead code.
+
* hurd/Versions (libc: GLIBC_2.2.5): Add _hurd_port_set,
_hurd_port_init, and __hurd_self_sigstate.
