/* INLINE CODE SELECTION:
GCC -O3 attempts to inline any function or procedure in scope. The

consequence) also eliminate further dead code.

+ On a CISC (x86) I've found that I can achieve an order of magnitude
speed improvement (x3-x5). In the case of RISC (sparc) while the
performance gain isn't as great it is still significant.

combined.
- 1 Include the C file for the module into the file being compiled

+ Include the C file for the module into the file being compiled
but do not make the functions within the module inline.
While of no apparent benefit, this makes it possible for the
included module, when compiled to inline its calls to what
would otherwize be external functions.
- 2 Make external functions within the module `inline'. Thus if
+ INLINE_MODULE:
+
+ Make external functions within the module `inline'. Thus if
the module is included into a file being compiled, calls to
its funtions can be eliminated. 2 implies 1.
- 4 Make internal (static) functions within the module `inline'.
