A bit of googling showed that strndup does appear in the "Linux
standards base", but it is not to be found in the Single Unix Spec.
That makes it at most quasi-standard IMHO.

Like Bruce, I'd like to see a more convincing use-case before adopting
not-very-standard functions.  I don't think people will expect pstrndup
to exist, or be very likely to use it if it's there, or necessarily know
what its behavior is (for sure I was confused by the naming similarity
with strncpy).  That's a lot of strikes for something that replaces only
three lines of C ...
