I would presume that the precompiled libraries are OK until
proven
otherwise. I didn't look for precompiled libraries, so I am
not certain
how the patches that they used to compile for MingW differed
from what I
posted. To keep the binary file compatible with Win98, I
would try to
ascertain that they are not dependent on any system files
only available
with WinNT/Win2K/WinXP.

When I put together the guide, I had forgotten to mention
the patch
necesary to make lynx function with PDCurses 2.7 or 2.8. By
using 2.6,
you avoid the need for that patch (which I hope will be
included in
dev.19).

OpenSSL uses the environment variable SSL_CERT_FILE to
indicate where
the collection of trusted certificates resides. How does
GnuTLS find the
file if it isn't in the default location which was compiled
in?

On the version that I compiled, the character set conversion
worked
correctly in fullscreen mode, using the DOS codepages, for
all
combinations that I tried, but sometimes gave wrong
characters in
windows mode. I'll try again with the latest versions
(gettext-0.15 and
libiconv-1.11 to see if that makes any difference.

That should work.

I dont' have those libraries on my machine. Are they
bundled with
GnuTLS?

OK.  Thanks.

I don't know well but I suspect that Lynx with GnuTLS
doesn't refer
the certificate files because it doesn't show any warnings
to the site
which has self-signed certificate.
If it's true, the binary with GnuTLS is inferior to the one
with OpenSSL
on this point.

Those are libraries on which are depended by GnuTLS.
I wanted to say that I don't know why the configure script
doesn't add
them to LIBS automatically like gnutls itself.

Like I said. (And the other issue with the DN format is
still open,
although I've sent a patch to Tom about it which none of
you GNU
users seems to have tested.)

I wrote a patch to improve this point.
After applying this patch, Lynx with GnuTLS verify the
server's
certificate.  Note that users must set the environment
variable
SSL_CERT_FILE to verify properly.

I also tried the patch which is posted by Thorsten Glaser on
5 Jul
against DN format probrem.  It suppressed the unexpected
message for
normal https sites as far as I tested Lynx with GnuTLS. 
Unfortunately
I couldn't test abnormal https sites, which doesn't have
CN, because I
don't know their URLs.

thanks (I merged it in last night to my interim patch, have
some additional
work to do in that area).  At the moment, I think that I've
addressed all of
the display issues that I intended for the next patch, and
have only some minor
work left to do.
