20cf41aa94 Clean this up a bit: 
* Abstract the conditional for immediate port numbers, and make it always
false if not optimizing.
* Add some whitespace to the string functions to make them more readable.

f86410093b Changed name of __weak_reference() to __indr_reference(). They really 
are indirect references, and I want to add a real __weak_reference()
macro to <machine/cdefs.h> soon.

b8403d582b don't be so quick to cast macro arguments to unsigned; if the 
arguments are really off_t's (e.g. to btodb), then you can lose
information.  This was the "> 4G file systems don't work" bug; physio
uses btodb, which was broken.

9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros 
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
