Building egcs-1.1b with ada/gnat-support failed

[ajung@du9ds9.fb9dv.uni-duisburg.de]

Hello all,

anybody have an idea, why I get the following error upon building the
gnat part of the egcs compiler ? (the error comes up, when the gnat1
program is being linked) :
------------------------------------------------------------------
../toplev.o: In function `main':
/usr/src/egcs-1.1b/gcc/toplev.c:4223: undefined reference to `lang_init_options'
a-misc.o: In function `yyparse':
/usr/src/egcs-1.1b/gcc/ada/a-misc.c:130: undefined reference to `__builtin_setjmp'
a-raise.o: In function `__gnat_raise_nodefer_with_msg':
/usr/src/egcs-1.1b/gcc/ada/a-raise.c:120: undefined reference to `__builtin_longjmp'
make[2]: *** [../gnat1] Error 1
make[2]: Leaving directory `/usr/src/egcs-1.1b/gcc/ada'
make[1]: *** [gnat1] Error 2
------------------------------------------------------------------
Everything else has been done according to the file README.gnat,
as mentioned in the FAQ. Compiler is currently a gcc-2.7.2.3 with 
compiled-in gnat support on a RedHat-5.0 linux distribution (i386).

Any comments / help is greatly appreciated,

Andreas
