Failure compiling langhooks.c on irix6.5

[Billinghurst, David (CRTS)]

On irix6.5 with cc, I get 

cc -c  -DIN_GCC    -g    -DHAVE_CONFIG_H    -I. -I.
-I/exd4/billingd/src/gcc-mainline/gcc
-I/exd4/billingd/src/gcc-mainline/gcc/.
-I/exd4/billingd/src/gcc-mainline/gcc/config
-I/exd4/billingd/src/gcc-mainline/gcc/../include
/exd4/billingd/src/gcc-mainline/gcc/langhooks.c -o langhooks.o
"/exd4/billingd/src/gcc-mainline/gcc/langhooks.c", line 129: error(1119): 
          return value type does not match the function type
    return copy_decl_for_inlining (res, fn, caller);
           ^

This occurs since there is no prototype for copy_decl_for_inlining .  The
following patch allows compilation to continue.
