* 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>. * 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.
