SVIDR4 may be a superset of POSIX.1(I am not sure that V.4 will pass
FIPS PCTS as it comes out of the box from USL) but V.4 is not
conformant to POSIX.(2,4...) Various other vendors with propritary OS's
are POSIX compatable without being at all compatable with SVID.

So it is unadvisable to concider SVID and POSIX to be the same.
