assembler is:

book2:libgcc jay$ file /obj/gcc.2/./gcc/as 
/obj/gcc.2/./gcc/as: Bourne shell script text executable
jbook2:libgcc jay$ /obj/gcc.2/./gcc/as  -v
GNU assembler version 2.23.90 (alpha-dec-vms) using BFD version (GNU Binutils)
2.23.90.20130918


sed is:

jbook2:libgcc jay$ sed --version
GNU sed version 4.2.1


I can try updating that.


jbook2:libgcc jay$ uname -a

Assembler warnings I think are rare and strongly to be avoided.
Maybe some of this follows from the sed warning. I'll have to dig into that.
Maybe #include <lib$routines.h> or other for the implicit declarations?
