Currently, trunk fails to boot fortran on hpux because of the following error:

../../gcc/gcc/fortran/parse.c: In function 'void unexpected_eof()':
../../gcc/gcc/fortran/parse.c:2618:1: error: 'noreturn' function does return [-W
error]
The attached patch fixes the above by adding the noreturn attribute to the
"longjmp" declarations in setjmp.h.
Okay for trunk?
