Unfortunately, I don't have the time to hack on it right now... have to get
back to real work and housebreaking the new puppy. :)
I made it into real patch. PROBLEMS file is not exactly
clear about what version is OK and what version is not.
Does egcs 1.0 means from egcs-1.0 to egcs-1.0.3a?
Also, I don't have access to systems other than Solaris 2.6
(sparc), Debian GNU/Linux potato (i686) and RedHat Linux 5.2
(sparc), so I cannot test on other platforms. egcs test is
not tested yet because I don't have egcs here.
Could someone please test this patch before I send it to
xemacs-patches? You need to run autoconf after applying this
patch. Thanks.
