inet_ntoa bug under Irix n32



Dear Sir/Madam,

I've investigated a little in the anoying inet_ntoa bug under SGI Irix.
I've come up with the following solution;

You could include the inet_ntoa.c from the following URL:
http://www.mit.edu/afs/athena/system/vax_bsd43/srvd/usr/sipb/src/xarchie-2.0
.10/inet_ntoa.c

a test program from egcs configureation file (as included) resulted in the
following line in the conftestval file:

Desk02 49# cat conftestval
1.2.3.4

It seems the bug has gone!
I hope you will include this "patch" in the upcomming releases.

With regards,

Erik Hofman
