Which Flash SWF compiler uses compiler directives?

Any existing Flash SWF compilers that can understand directives like #IF #ENDIF, etc?

Some SWF Compilers: (Hopefuls)

• AS3 Compiler - Haxe
• AS2 Compiler - MTASC
• Adobe Flex Compiler - Mxmlc
• C# to SWF Compiler - Debreuil

I've used mtasc, and it does not support this kind of conditional compilation. However, it looks like Flex 3's mxmlc has support for this via the -define command line option. Also, Haxe does exactly what you want.
