There is no fully-functional equivalent to "ftruncate()" in any flavor
of vanilla S5, which makes it unlikely that anybody's produced a version
of them for S5 - the hooks just aren't there.  "sigsetmask" also
requires a more powerful signal mechanism than existed prior to S5R3; it
might be possible to do some or all of "sigsetmask" atop S5R3, but it's
not posssible to do it atop the signal mechanism that existed prior to
that.
