* 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.
