Does it work if you add the following to src/s/sco5.h?

#define SIGMASKTYPE int

Because I don't want to risk breaking other platforms because of a
problem that is specific to SCO 3.2.5.  I'd prefer a change that only
affects that single system.

Specifically, some of the branches of syssignal.h that define
sigblock and sigunblock seem to imply that some of the systems have
SIGMASKTYPE defined in their system headers.  So I don't want to mess
with those other systems.
