Please check for potential regressions.

In the function ExecuteCommand, p_message is given in argument to ExecuteHelp
and is then modified locally in ExecuteHelp:
  p_message = vlm_MessageNew( "help", vlm_NULL );
whereas it is used further in function ExecuteCommand.
This patch fixes this problem by passing the pointer address in argument to
ExecuteHelp instead of the pointer itself.

...in addition to vlc-config

Only enable those modules that were enabled, rather than _all_ of them
(which should fix --disable-sse and --disable-mmx). Also don't run
checks if we know we're not going to enable the modules anyway.

sorry about the disturbance

Hack to fix the compilation on 10.4. This should actually be covered by configure, which complains about missing headers, but doesn't disable this module properly.

Reverted 4082c803 as AudioDeviceIOProcID and its related methods require Darwin 9

Clueful people use them when they need to. Let them decide.
