problem in compiling GCC cross compiler

["Modi Banti" <b dot modi at sssup dot it>]

Hello,

I am trying to compile gcc-3.3.2 for ARM processor. I am 
using binutils2.11.2. I am listing the steps which I am 
following in order to get it compiled.

1) I unzipped all tar files.

2) I build the binutils as follows-

   cd binutils-2.11.2
    ./configure --target=arm-elf --prefix=$HOME/ARM7
   make 
   make install

3) cd ../gcc-3.3.2/
   ./configure --target=arm-elf --prefix=$HOME/ARM7 
--with-newlib

   export PATH=$HOME/ARM7/bin:$PATH

   till here everything is perfect but now when I try to 
make it 

  make 
  I get the following error 

  make[1]: Entering directory 
`/users/students/tesi10/gcc-3.3.2/arm-elf/libiberty'

regex.c:53:25: sys/types.h: No such file or directory
regex.c:151:24: string.h: No such file or directory


I verified that sys/types.h and string.h files are present 
in /user/include directory. I am not sure why gcc is not 
looking in that directory. can you please help me in 
fixing this.

Thanks and regards,
