How to suppress warnings for one ActionScript file?

I've got an ActionScript 3 source file (.as) that has hundreds of untyped variables. This file works perfectly although it outputs a warning for every untyped variable which gets me ~800 warnings clogging the Error panel in my IDE.

Although warnings are helpful in my other source files, I want to suppress warnings for this one .as file, because I'm in no mood to specify data types for them all.

Is this possible?

I'm using FlashDevelop 3 on Windows 7,
and compiling an AS3 AIR project using the Flex 4 SDK.
