I've run into the same problem. The lpCommandLine string in the win32
CreateProcess() function is limited to 32Kb. When the string gets larger
than the limit, the process creation fails.

I solve this by creating archives of the *.o files (for example, per
namespace) with ar; and link the resulting *.a files:

  <target name="archive">
        <apply failonerror="true" executable="ar" parallel="true">
            <fileset dir="obj/namespace1" includes="**/*.o"/>
            <arg line="-cr arc/namespace1.a"/>
       </apply>
        <apply failonerror="true" executable="ar" parallel="true">
            <fileset dir="obj/namespace2" includes="**/*.o"/>
            <arg line="-cr arc/namespace2.a"/>
       </apply>
    </target>

  <target name="link">
        <apply failonerror="true" executable="gcj" parallel="true">
            <fileset dir="arc/" includes="*.a"/>
            <arg value="--main=myMain"/>
            <arg line="-o exe/myexe"/>
            <srcfile/>
       </apply>
    </target>
