[MPlayer-dev-eng] [PATCH] EH_prolog docu/simplification

[Reimar D?ffinger]

Hello,
the attached patch simplifies and documents the exp_EH_prolog function.
I'm not sure if the change is a good idea, on the one hand this new
version IMO is much easier to understand, on the other hand the old
version is closer to the MSVCRT original...
Unfortunately I see no way to convert this into proper inline asm, at
least not without some hackishness :-(

Greetings,
Reimar Döffinger
