Compile Flags for API & Client code:

-c
	Directs cc to suppress linking with ld(1) and to produce a .o file
	for each source file.

-G
	Passes the option to the link editor to produce a shared object rather
	than a dynamically linked executable.

-Dname[=tokens]

	Associates 'name' with the specified 'tokens' as if by a #define
	preprocessing directive. If no '=tokens' is specified, the token 1
	is supplied.

-x04
	Generate level 4 optimized code. 

	-x01 does basic local optimization (peephole).

	-x02 does basic local and global optimization.

	-x03 performs like -x02 but also optimizes references or definitions
	for external variables. Also does loop unrolling and software
	pipelining.

	-x04 performs like -x03, but also automatically inlines functions
	contained in the same file.

-xchip=chip

	Specify the target processor for use by the optimizer. The 'chip'
	option can be one of the following: generic, old, super, super2,
	micro, micro2, hyper, hyper2, powerup, ultra, ultra2, ultra2i, 386,
	486, pentium, pentium_pro, 603, and 604.

	The option 'ultra' enables the compiler to consider timing properties
	of the UltrSPARC processor when generating code.

-xarch=isa

	Specify the instruction set architecture. For SPARC, 'isa' can be one of
	the following: generic, native, v7, v8a, v8plus, v8plusa, v8plusb.
	v9, v9a, and v9b.

	The option 'v8plusa' enables the compiler to generate code good for
	performance on the UltraSPARC architecture, but limited to the 32-bit
	subset defined by the V8plus specification.
