B.2.3 -Aname[(tokens)]

Associates name as a predicate with the specified tokens as if by a #assert preprocessing directive. Preassertions:

• system(unix)

• machine(sparc) (SPARC)

• machine(i386) (x86)

• cpu(sparc) (SPARC)

• cpu(i386) (x86)

These preassertions are not valid in -Xc mode.

If -A is followed by a dash (-) only, it causes all predefined macros (other than those that begin with __) and predefined assertions to be forgotten.
