It should do, yes.
But the comment in the irix.h file seems to indicate that
(at least on some versions of IRIX), these tests weren't working
properly - hence needing to hardwire the "correct" results.
It may be that later amendments to the configure script may
have fixed this problem - but a bug-fix release isn't the time
to find out.
Thomas has applied your patch to the main development code,
so the 5.3 release process should hopefully catch any problems
with earlier IRIX systems (assuming there's someone who can
try this out!)

Checking the history, the suppression of <arpa/inet.h> dates
from November 2001 (as does the explicit inclusion of
<netinet/{tcp,ip}.h>) - though the explanation was only added
some time later.
The explicit declaration of 'inet_ntoa()' is clearly a
consequence of not including <arpa/inet.h>
What is the definition of inet_addr() in <arpa/inet.h> ?
