No idea.

Since you have a working version, albeit ancient, it would be useful if 
you could find out the exact version *including prereleases* which is 
the last one working.

Even better, if you're comfortable with "git bisect", pull the git tree 
and try to bisect:

git clone git://git.kernel.org/pub/scm/boot/syslinux/syslinux.git
cd syslinux
git bisect start
git bisect good
git bisect syslinux-2.04

Then:
make spotless && make
make bisect {good|bad}

... repeat until done ...

Unfortunately, it's easy to land at an "unbisectable" spot :(

If so, it helps to narrow down the "good/bad" range by trying releases 
and prereleases as I mentioned above.
