The new version of POSIX.1, IEEE Std 1003.1-1990, came out last
December.  You can get it from the IEEE; their number is 1-800-678-IEEE,
and I think that the order number is SH13680.  It uses ANSI C prototypes.
execvp(), for example, is:

	int execvp(const char *file, char *const argv[]);

It also has quite a number of other "bug fixes".

ANSI C "wasn't" when the 1988 version of POSIX was written.  There were
drafts of the C standard around, but it wasn't approved, and there was no
guarantee that it wouldn't change.  That was the main reason for staying
with the traditional syntax.
