Re: i386-pc-solaris2.5.1: recent snapshots can't build emacs-20.2

[Jim Meyering <meyering at ascend dot com>]

Hi,

I have just confirmed that current sources as of about 980714-08h24
still exhibit the problem I reported three weeks ago.  For all I know,
this could be a problem with emacs, solaris5.5.1, or some tool in my
build environment.

Has anyone built a recent version of emacs (20.2 or newer test releases)
with an egcs snapshot from June or later?
