Well, the conclusion ("there will be [f]truncate in S5R4") is, as far as
I know, true, but it has nothing to do with the premise:

	1) if by POSIX you mean 1003.1, neither "truncate" nor
	   "ftruncate" appear as specified functions - period;

	2) if by POSIX you mean some under-development 1003.N, they
	   haven't been ratified (or whatever it is you do to stamp a
	   standard Property of the Zoo) yet, so AT&T isn't *obliged* by
	   those standards to provide it.
