CURRENT's GCC supports both ISO C variadic macro syntax and its own.
The latter is also supported in STABLE's GCC.  I imagine ICC supports
at least ISO C syntax and possibly also the old GCC syntax, since it
tries to be GCC-compatible, and that both TenDRA and Watcom support
the ISO C syntax.  See src/contrib/openpam/include/security/openpam.h
for an example of code that selects the right syntax depending on what
the compiler is expected to support.
