[syslinux] SYSLINUX 3.73-pre1 (RC)

[H. Peter Anvin]

I have pushed out SYSLINUX 3.73-pre1.  It only contains the build fixes 
that have accumulated since 3.72, and a version bump of gPXE to the 
equivalent of the 0.9.5 gPXE release.

Given the number of people who have had build problems, I'm making this 
a release candidate, with the intent of pushing out 3.73 as a minor 
fixes release only.  If you have the ability to test 3.73-pre1, 
especially if you have access to platforms other than what I have, 
please do so.
