DJGPP used in cc task, Dos 126-characters limit ?

All,

When I use DJGPP's gcc to be the compiler of cc task, it can not process the
long command line.
As I know, DJGPP's make can process it. But I just want to use gcc to
compile the c source files.

  <target name='debug' depends='init' description="Build all source to get
library out">
    <mkdir dir="${build.dir}/objs_d"/>
    <cc name="${cc}" objdir="${build.dir}/objs_d"  outfile="test"
outtype="static">
      <compiler extends="${cc}-compiler">
        <includepath location="${proj.root}/include"/>
        <includepath location="${proj.root}/include/rtos/include"/>
        <includepath location="${proj.root}/include/openssl/inc32"/>
        <defineset>
          <define name="SHORT_PACKET"/>
          <define name="DEBUG_ENABLE"/>
          <define name="CPU_64BITS" if="is-64bits"/> 
        </defineset>
        <compilerarg value="-g3"/>
        <compilerarg value="-Os"/>
      </compiler>
      <linker refid="${cc}-linker"/>
      <fileset dir="${proj.root}/src" includes="*.c"/>
    </cc>
  </target>

The generated command line will exceed 126 characters. Ant will report error
87, Could not launch gcc.
If I reduce some macros and include paths, then it will work.

Any help would be appreciated.

Best regards,
Ming
