compiling problems (getting started)

Hi,

As a newbie in RTEMS, I have a problem in compiling the cross-compiler.

I'm using a Debian Linux system (kernel 2.0.X) on a i386 and I want to
target to i386 WITH gnat-support.
I patched gnat3.10p, binutils, newlib, etc. and now I tried to run the
ada_bit script.  After a while, this returns with:


              `if [ xobstack.o != x ]; then echo ../obstack.o; else true;
fi` `case "gcc" in "cc") if [ x != x ]; then echo ../; else true; fi ;;
esac` `if [ x != x ]; then echo ../; else true; fi` 
a-misc.o: In function `yyparse':
a-misc.o(.text+0x16): undefined reference to `__builtin_setjmp'
a-raise.o: In function `__gnat_raise_nodefer_with_msg':
/opt/ROBOTHOME/RTEMS/tools/build-i386-tools/gcc/ada/../../../src/gcc/ada/a-raise.c:120:
undefined reference to `__builtin_longjmp'
make[1]: *** [../gnat1] Error 1

Does anyone has a suggestion ?

Also a second question about the docs.  As I understand it, you can build
a GNAT/RTEMS system INDEPENTENTLY of a C(++)/RTEMS system, so you don't
have to build the C++ crosscompiler in order to build the Ada-equivalent.
IS THIS CORRECT ?

I would really appreciate any useful input, because I'm really interested,
but not very experienced ... THANKS !!
