gcc build fails "cannot compute suffix of object files"

[chenyulongrtems]

 Hi all !
    I'm building arm toolchain for rtems-4.10, when building gcc-4.3.2 I meet a problem .
    My pc is RHEL4 , and my sources is :
    binutils-2.19-rtems4.10-20081023.diff
    binutils-2.19.tar.bz2
    gcc-core-4.3.2-rtems4.10-20081119.diff
    gcc-core-4.3.2.tar.bz2
    newlib-1.16.0.cvs.20081127-rtems4.10-20081127.diff
    newlib-1.16.0.cvs.20081127.tar.gz
 
 
    when make gcc it fails as:

In config.log, I then see:

conftest.cc: In function `int main()':
conftest.cc:13: error: `exit' undeclared (first use this function)

configure:4089: $? = 1
configure: failed program was:

| #define PACKAGE_NAME ""

| /* end confdefs.h.  */
| 
| int
| main ()
| {
| exit (42);
|   ;
|   return 0;
| }

Any ideas about what I need to fix?

Thanks,
