Compiler.define in flex-config and compc

Question

I'm having an issue with compile time constants.  I'd like to define these constants in two places, but when I do the flex compiler forgets constants defined in my flex-config.xml (DEBUG::DEBUGGING and DEBUG::VERBOSE).  I am using flextasks.tasks in ant to build the project.
In my build.xml:
<target name="build-project" depends="init">
    <echo message="Building ${proj.swc.file}" />
    <compc output="${proj.target.dir.bin}/${proj.swc.file}"
        target-player="${proj.flashver}">
        <compiler.define name="INFO::VERSION_MAJOR" value="${proj.version.major}" />
        <compiler.define name="INFO::VERSION_MINOR" value="${proj.version.minor}" />
        <compiler.define name="INFO::VERSION_RELEASE" value="${proj.version.release}" />
        <compiler.define name="INFO::BUILD_TIMESTAMP" value="${proj.build.timestamp}" />
        <compiler.define name="INFO::BUILD_TIMEZONE" value="${proj.build.timezone}" />
        <load-config filename="${mx.sdk.dir}/frameworks/flex-config.xml"/>
        <load-config filename="${basedir}/flex-release-config.xml"/>
        <source-path path-element="${proj.build.dir.src}" />
        <include-sources dir="${proj.build.dir.src}" includes="**/*.as **/*.mxml"/>
        <!-- <compiler.external-library-path dir="${proj.build.dir.lib}" includes="*.swc" append="true" /> -->
        <compiler.external-library-path dir="${proj.target.dir.lib}" includes="*.swc" append="true" />
    </compc>
</target>
In flex-release-config.xml:
<flex-config>
    <compiler>
        <debug>false</debug>
        <keep-generated-actionscript>false</keep-generated-actionscript>
        <verbose-stacktraces>false</verbose-stacktraces>
        <optimize>true</optimize>
        <define>
            <!-- Enables debugging mode -->
            <name>DEBUG::DEBUGGING</name>
            <value>false</value>
        </define>
        <define>
            <!-- Provides more information to the developer -->
            <name>DEBUG::VERBOSE</name>
            <value>false</value>
        </define>
    </compiler>
</flex-config>
If I compile using compc on the command line I can use -define+=NAME,value and it works.  Why is it not working using the compc task in ant?

Try adding the append="true" attribute to the define elements. I'm not sure if this will work, but that's how it works (append="true" is the equivalent of +=) for other elements like external libraries.
