This enables the same OpenSP warnings on osx calls that we get from onsgmls (make check) and formerly from openjade.
Older tool chains apparently have some of these warnings on by default (see comment at SPFLAGS assignment). So users of such tool chains would complain about warnings or errors that users of newer tool chains would not see, unless they used "make check".
