Strange, it wasn't doing that for me, but perhaps that's because I was 
using gcc-3.x?

The change was made because certain systems have serious problems 
between the included regex and the system regex. We were told that there 
were segfaults with the included regex.h (prob. because it was receiving 
precedence in the INCLUDES) and the system libc's regex code. Their 
solution was to move regex.h to gregex.h. Since it doesn't matter much 
to *us*, that seemed fine.

Loops are quite possible with symlinks (though what you describe is a 
bug). This is why the checksumming code is important.

Yes, I'd think that's a problem. Would it be easier to handle a symlink 
as a redirect?

The HtFTP class was started by a contributor and I haven't seen any 
further evidence that it's been completed. So no, it doesn't handle 
ftp:// URLs, nor should it be "hooked up" in Document.cc.

My understanding is that the newest versions of automake really need to 
use the most current versions of autoconf as well. I don't believe the 
configure.in has been updated for autoconf-2.5x. As well, you need to 
run "aclocal" usually to update that file with a variety of 
automake/autoconf macros.

Yes, sorry. I'm wading through a huge e-mail backlog. :-(

Send me an e-mail with your SourceForge account and I can turn it on.
