[PATCH] New hpux fix to add noreturn attribute to longjmp declarations in setjmp.h

[John David Anglin]

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

/xxx/gnu/gcc/objdir/./prev-gcc/xg++ -B/xxx/gnu/gcc/objdir/./prev-gcc/ -B/opt/gnu64/gcc/gcc-7/hppa64-hp-hpux11.00/bin/ -nostdinc++ -B/xxx/gnu/gcc/objdir/prev-hppa64-hp-hpux11.00/libstdc++-v3/src/.libs -B/xxx/gnu/gcc/objdir/prev-hppa64-hp-hpux11.00/libstdc++-v3/libsupc++/.libs  -I/xxx/gnu/gcc/objdir/prev-hppa64-hp-hpux11

../../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?
