cygwin -> mips GCC_NO_EXECUTABLES error

[Matt Snoby]

 Hi CrossTools mail list, 
For the past couple of weeks I’ve been trying to  create a mips gcc 4.1.0 tool chain that runs under a cygwin environment.  I've gotten a 3.4.4 toolchain to build, however not a 4.1 tool chain.  I’ve worked past quite a few issues, but I’ve finally run into one that I just can’t seem to get past.  I’ve consulted the almighty google and  the mail list, but have yet to find a solution.   
The build fails while configuring for the libstdc++-V3  (If you need more of a log I can reply with that, I just didn't want to make the msg too long).
  
checking for shared libgcc... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. 
make[1]: *** [configure-target-libstdc++-v3] Error 1 
make[1]: Leaving directory `/usr/mybuild/crosstool-0.42/build/mips-linux/gcc-4.1.0-glibc-2.4/build-gcc-core 
   
 I’ve searched on the net and after consulting Martin Guy’s website,  ( I applied his ports and nptl patch)I thought all I had to do was add: 
GCC_EXTRA_CONFIG=--disable-multilib 
 
 to the mips.dat file, however this had no effect. 
 I did the following steps to create this build: 
  
1.) created a gcc-4.1.0-glibc-2.4.dat file 
    BINUTILS_DIR=binutils-2.16.91.0.7 
    GCC_DIR=gcc-4.1.0 
    GLIBC_DIR=glibc-2.4 
    LINUX_SANITIZED_HEADER_DIR=linux-libc-headers-2.6.12.0 
    GLIBCPORTS_FILENAME=glibc-ports-2.4 
    GLIBC_ADDON_OPTIONS=ports,nptl 
    GDB_DIR=gdb-6.3 
   
 2.) Modified the mips.dat file 
    KERNELCONFIG=`pwd`/mips.config 
    TARGET=mips-linux 
    TARGET_CFLAGS="-O2 -finline-limit=10000" 
    GCC_EXTRA_CONFIG=--disable-multilib 
   
 3.) Modified the demo-mips.sh file: 
    #!/bin/sh 
    set -ex 
     # Big-endian MIPS 
     TARBALLS_DIR=$HOME/downloads 
    RESULT_TOP=/opt/crosstool 
    export TARBALLS_DIR RESULT_TOP 
    GCC_LANGUAGES="c,c++" 
    export GCC_LANGUAGES 
    BINUTILS_EXTRA_CONFIG=--disable-werror 
    export BINUTILS_EXTRA_CONFIG 
    CYGWIN_DIR=cygwin-1.5.21-2 
    #should give it a place to download the cygwin source.... but  
    #I just put it in the download directory. 
    export CYGWIN_DIR  
    QUIET_EXTRACTIONS=1 
    export QUIET_EXTRACTIONS 
  
  
    # Really, you should do the mkdir before running this, 
    # and chown /opt/crosstool to yourself so you don't need to run as root. 
    mkdir -p $RESULT_TOP 
     # Build the toolchain.  Takes a couple hours and a couple gigabytes. 
  
    ## This works for  3.4.4 tool chain 
    #eval `cat mips.dat gcc-3.4.4-glibc-2.3.5.dat`        sh all.sh --notest 
     ## This is for the 4.1.0 toolchain 
    eval `cat mips.dat gcc-4.1.0-glibc-2.4.dat`        sh all.sh --notest 
    echo Done. 
   
 Any suggestions on how to get past this? 
 Thanks,
