Possible issue with compiler flag values

I'm seeing some strange behavior with -D compiler flags with values:

If I use -D myvar=myval, I'm getting the name of the define, but not the value.

[awhite@acw][~/temp/haxe-test][2098][0]>>> haxe -v -D myvar=myval build.hxml | head
Classpath : ./;/usr/local/lib/haxe/std/js/_std/;/usr/local/lib/haxe/std/

It simply doesn't print it there. What's the actual issue?

In the code, I'm trying to check the value in an #if, but it does not seem to be working

haxe -D env=dev build.hxml

#if (env == "dev")
... do something
#else
...
#end

It doesn't seem to get into the #if block, it falls through to the #else. I've tried various ways of quoting the command line args, and not quoting the value in the #if

Please post a complete example with a .hx and .hxml file.

Ok, I just tried it with a simple example and it's working right... not sure what's going on in my project. Will post a new issue if I can narrow it down. Sorry for the hassle.

Actually we should make -v print the values too.
