Dear All,

We are trying to build a cross gcc which will be hosted on cygwin and produce
binaries for Linux/x86. our setup is as below :

1. We are building crossgcc tool chain for the following :

    host  - cygwin
    build - cygwin
    target- Linux(x86)

 meaning, a crossgcc built on CYGWIN, hosted on CYGWIN, but to produce
code 
 that will run on Linux/x86 platform.

2. our environment is as below :

   Windows 98/ CYGWIN release 1.3.21 / i686


3. built and installed binutils .ok(with warnings).............

tar jxf source/binutils-2.12.tar.bz2
    pushd binutils-2.12
    mkdir build-${CHIP}-linux
    pushd build-${CHIP}-linux
    LDFLAGS='--static' CFLAGS='--static'
    ./configure \
        --target=i686-pc-linux-gnu \
--host=i686-pc-cygwin \
        --build=i686-pc-cygwin \
--prefix=${PRO_INSTALL_PREFIX} ${FP}

    make
    make install

4. we are trying to build and install glibc2.1.3 and we are getting error as
below

5. further when we are trying to build gcc, we are getting the errors
   that say stdlib.h and unistd.h missing when compiling libgcc2.c

We are not using newlib here. Please let us know, if you have come across
this problem or we are doing something wrong.

Regards,

Babu K
