2) Add __RCSIDs where apropriate.
3) WARNS=1, and clean up sources for WARNS=1 (including replacement of
a mktemp with a mkstemp even though it was probably safe...)
4) Some other small cosmetic changes
probably never be completely supported here (since its internal vs.
external symbol handling is so annoying), but at least we can recognize
the ECOFF binaries and print something useful, on machines that use
them.
