The expanded sources for os_io.c on RHEL 4.2 show
> # 23 "/usr/include/bits/sigset.h" 3 4

then

then

and gcc rightly complains:
> gcc -I../include -I. -Wall -W -Wno-unused -O1 -fno-math-errno -
> fschedule-insns2 -fno-trapping-math -fno-strict-aliasing -fwrapv -

So I suggest you change os_io.c from
> ___HIDDEN sigset_type block_signal
> ___P((int signum),
> (signum)
> int signum;)
> {
> sigset_type oldmask = 0;
to
> ___HIDDEN sigset_type block_signal
> ___P((int signum),
> (signum)
> int signum;)
> {
> sigset_type oldmask;
