Conditional compilation "else"

Question

In AS3 you can pass a constant to the compiler

-define+=CONFIG::DEBUG,true 

And use it for conditional compilation like so:

CONFIG::DEBUG {    trace("This only gets compiled when debug is true."); } 

I'm looking for something like #ifndef so I can negate the value of debug and use it to conditionally add release code. The only solution I've found so far was in the conditional compilation documentation at adobe and since my debug and release configurations are mutually exclusive I don't like the idea of having both DEBUG and RELEASE constants.

Also, this format works, but I'm assuming that it's running the check at runtime which is not what I want:

if (CONFIG::DEBUG) {    //debug stuff } else {    //release stuff } 

I also considered doing something like this but it's still not the elegant solution I was hoping for:

-define+=CONFIG::DEBUG,true -define+=CONFIG::RELEASE,!CONFIG::DEBUG 

Thanks in advance :)

This works fine and will strip out code that won't run:

if (CONFIG::DEBUG) {    //debug stuff } else {    //release stuff } 

BUT this will be evaluated at runtime:

if (!CONFIG::DEBUG) {    //release stuff } else {    //debug stuff } 

mxmlc apparently can only evaluate a literal Boolean, and not any kind of expression, including a simple not.
