Re: broken `sigblock' defns

No.  `SIGMASKTYPE' is defined in "syssignal.h" which should be
affected by "config.h" with "s/" files, all of them included before
"syssignal.h".  You try to use `SIGMASKTYPE' in "s/" file before it is
defined.

Remember, "sysdep.c" defines `sigprocmask_set' var unconditionally, so
`SIGMASKTYPE' defn also gets available to it unconditionally, which is
ensured by "syssignal.h".  So why not declare `sigprocmask_set' in
that same "syssignal.h" once and for all, unconditionally?
