Embedded fonts not displaying when building project via mxmlc

Question

I have a flex 3 project and I'm trying to upgrade it to flex 4.6 sdk. I have a number of embedded fonts in my application. These display fine when I build via Eclipse/Flash builder. When I build using mxmlc the embedded fonts are not being used. I build the fonts in the same way for both so I am assuming there is some compiler option which I am missing, or which I have that is causing the problem. I've tried every compiler option I can think of and now I'm at a dead end...
<target name="compile" depends="getswcs, compilemodules"> 
     <echo message="mxmlc=${mxmlc}"/>
     <echo message="flex.lib.dir=${flex.lib.dir}"/>
     <echo message="flex.extlib.dir=${flex.extlib.dir}"/>
     <echo message="flex.locale=${flex.locale}"/>
     <echo message="flex.locale.dir=${flex.locale.dir}"/> 
     <exec executable="${mxmlc}" dir="${basedir}" failonerror="true">
          <arg line="'src/${main}'" />
          <arg line="-o 'bin/${component.lowercase.name}.swf'" />
          <arg line="-l+='${flex.lib.dir}'" />
          <arg line="-sp src" /> <arg line="-accessible" />
          <arg line="-strict" />
          <arg line="-el '${flex.extlib.dir}'" />
          <arg line="-compatibility-version=3.0.0" />
          <arg line="-target-player '11.1'" />
          <arg line="-include-libraries+=lib" />
          <arg line="-locale ${flex.locale}" />
          <arg line="-l+='${flex.locale.dir}'" />
     </exec> 
</target>
The compileModules builds my fonts, for example:
<exec executable="${mxmlc}" dir="${basedir}" failonerror="true">
     <arg line="fonts/OCRAEXT.as" />
     <arg line="-static-link-runtime-shared-libraries" />
     <arg line="-o bin/lib/OCRAEXT.swf" />
</exec>`
as file:
public class OCRAEXT extends Sprite {
     [Embed(source='OCRAEXT.TTF', fontName='_OCRAEXT', embedAsCFF='false', unicodeRange='U+0030-U+0039,U+002E,U+002F,U+20AC')]
public static var font:Class; }
I don't think there's an issue here, since the fonts are already built via my compileModules before building the application in Eclipse, where the fonts display correctly.

Try comparing SWF sizes and link-reports.
