Syslinux - Nov 2007 - 3.53-pre5 released - release candidate

Hi all,

I have received a fair number of bug reports over the last few weeks
-- even days -- and I am therefore declaring 3.53-pre5 a release 
candidate for a 3.53 bug fix release.

This 3.53 will not contain either of the two major features under 
development -- client side state (including boot-once) and gPXE 
integration -- since I want to avoid destabilizing the code base beyond 
the bug fixes/firmware workarounds that have been added.

Please try out 3.53-pre5 if you have the chance.  I would like to 
release 3.53 some time between Friday and Monday (Nov 16-19).

isolinux still locks under qemu.

Yep, it now works correctly.

I only started using the git version of nasm to debug my first report.

Do you wish me to continue testing syslinux + nasm periodically?

Absolutely.  It is highly useful, as we just saw, especially if you have 
the time to git bisect any failures.

Testing is highly appreciated...
