Building a crossgcc for m32r

[Matthias Hawran <matthias dot hawran at trialog dot com>]

Hi everybody,

I  went through the list, but i can't find an answer.

I'm trying to build a gcc for the m32r (mitsubishi) target, on a win 2k 
host.

I downloaded the gcc 3.3.1 complete sources.
I'm using :
- cygwin 1.3
- gcc 2.95.3-5
- as 2.11.92
- bash 2.05a.0(3)

My tree is :
gcc-3.3.1-build/
                      /src
                      /lib

I executed the following, in the lib dir:
> bash (starting a bash to execute configure)
> ../src/configure --target=m32r-elf
> exit (to quit bash)
> make


configure finishes ok

not make..
here is the error :

------------------------------------------


So 'as' doesn't regonize the option --no-warn-explicit-parallel-conflicts
If I remove the option (in a "specs" file), the same command fails.
It seems that "as" doesn't assemble for m32r...
If I tye "man as", I can read the following :

      The  following options are available when as is configured
      for the Mitsubishi M32R series.

      --m32rx
          Specify which processor in  the  M32R  family  is  the
          target.   The  default  is normally the M32R, but this
          option changes it to the M32RX.

      --warn-explicit-parallel-conflicts or --Wp
          Produce warning messages  when  questionable  parallel
          constructs are encountered.

      --no-warn-explicit-parallel-conflicts or --Wnp
          Do  not  produce  warning  messages  when questionable
          parallel constructs are encountered.


So my "as" knwos this option, but when it "is configured for the 
Mitsubishi M32R series."
That's my assumption... : "as" is some how not configured for M32R series...

I also tried the following configure :
../src/configure --taget=m32r-elf --with-gnu-as --with-gnu-ld

but the result is the same

any ideas?

thanks in advance

Matthias
