# The more unusual options to the Sun C compiler:

#	-v		Stricter type checking, more error checking

#			(To turn ALL warnings into fatals, use -errwarn=%all)

#	-xstrconst	Place string literals and constants in read-only area

#			(means you can't write on your string literals)

#	-xs		Force debug information (stabs) into the .so or a.out

#			(makes the library/executable debuggable without the

#			.o files needing to be around, but at a space cost)

#	-g & -O		If you add the -g option to the optimized compiles

#			you will get better stack retraces, the code is

#			still optimized. This includes a space cost too.

#       -xc99=%none     Do NOT allow for c99 extensions to be used.
