Hello.

Please find attached a patch to make getlogin() examine the USERNAME
environment variable. It does this after USER, LOGNAME. A what's changed
entry is also included. Before/if the patch is committed to CVS, could
someone please check that USERNAME is not set on Windows '98, so that the
texinfo doc is correct. (I do not have access to Windows '98.) I've
checked '95, NT, 2000.

Thanks, bye, Rich
