[syslinux] com32 compatibility between syslinux 3-4

[Ayvaz, James]

Hi Everyone,
                This question might be a long shot, but is it possible to mix and match com32 programs written against Syslinux 3 with com32 programs written against Syslinux 4 without recompiling.   We are trying to have our com32 programs run with different versions of Syslinux without modification.  Appreciate any advice,

thanks in advance.
