building the cross compiler does not find unistd.h and stdlib.h

[douglas <douglas at idiom dot com>]

  Hi

   I am trying to build a cross compiler on an ultra-sparc running redhat
6.2, for the i686 platform running linux as well.   I am using gcc-2.95.2,
binutils-2.10.0 and glibc-2.1.3.  I am not having luck building
gcc-2.95.2.  The build of gcc-2.95.2 can not find unistd.h and stdlib.h



Notes on the configuration:

The cross build process works well for binutils-2.10.0.  I used the
configuration parameters 

./binutils-2.10/configure --target=i686-linux --prefix=/cross/i686 -v

In a seperate directory, During the build of gcc-295.2 

./gcc-2.95.2/configure --target=i686-linux --prefix=/cross/i686
--with-headers=../glibc-2.13/include -v


Here is the output of the make all process for gcc-2.95.2...

In the above process I have also used newlib-1.8.2/newlib/include as well.
