It's not and never has been.
The most obvious example is its lack of the "Posix functions" that Korn
introduced in ksh93 to make it conformant. There are a number of other
non-conformant behaviors, even without considering bugs (for instance, I
believe the `test' builtin isn't conformant with the Posix number-of-
arguments algorithm, but I don't have a version handy to test).
