Problems with building GCC/GNAT as an Ada cross compiler

[pee at MIT dot EDU]

Hello all,

    I am trying to build GNAT to cross compile from host=i686-linux-pc to
target=powerpc-elf.  However, only gnatbind is available after building
everything.  There's no gnatmake, gnatfind, etc.  When I tried calling "make
gnatlib" and "make gnattools", it gave out some error messages.  I tried looking
through both crossgcc and chat@gnat archives but couldn't find anything on it. 
I wonder if anyone could help me out.  Thank you very much.

    Here is the configuration I'm using:

1. binutils-1.11.0
2. gcc-3.3
3. newlib-1.11.0
4. linux-2.4.20-20.9

    I followed Bill Gatliff's building script, and all these configure and make
didn't give me any error.  After that, I tried making gnatlib in order to build
gnattools afterwards, but I ran into this error:

     It was complaining that it couldn't find dirent.h in the include path
before, so I copied newlib-1.11.0/newlib/libc/include into the target include
path, and it could find dirent.h, but still gives out this error.

     Thank you very much for your help.

     Here is my build transcript if necessary.

  
*** build binutils ***

$ ../binutils-2.14/configure --target=$target --prefix=$prefix 2>&1 | tee
configure.log

$ make all install 2>&1 | tee make.log
  
                                                                            
*** build gcc-core ***

$ ../gcc-3.3/configure --target=$target --prefix=$prefix
--enable-languages=c,ada --with-local-prefix=$prefix/$target --without-headers
--with-newlib --disable-shared --with-gnu-as --with-gnu-ld --enable-threads
--host=i686-linux 2>&1 | tee configure.log

$ make all-gcc install-gcc 2>&1 | tee make.log


*** build newlib ***

$ ../newlib-1.11.0/configure --prefix=$prefix --target=$target 2>&1 | tee
configure.log

$ make all install info install-info 2>&1 | tee make.log


*** build gcc full ***

$ ../gcc-3.3/configure --target=$target --prefix=$prefix
--enable-languages=c,ada --with-local-prefix=$prefix/$target 2>&1 | tee
configure_full.log

$ make all install 2>&1 | tee make_full.log


    Here only gnatbind is available, so I go into gcc-3.3/gcc directory and
build gnatlib in order to build gnattools later on, but I got an error:

$ make gnatlib
