Implemented a similar workaround to the one I did for a gethostbyaddr_r()
2004-04-13 Jeffrey Stedfast <fejj@ximian.com>
* e-host-utils.c (e_gethostbyname_r): Implemented a similar
workaround to the one I did for a gethostbyaddr_r() glibc bug
here. Glibc will apparently return success for addresses such as
"192..168.1.1" (note the double dot) and yet not have filled in
the hostent properly.
