it means, that the c-code in CPMD is written in the old
so-called K&R style (i.e. pre-ANSI) syntax for maximum 
compatibility. by now all reasonable machines should be 
supporting ANSI C, so this would no longer be needed, but
as usual, it would need some volunteers to change and test
it. those warnings, however, are harmless (for as long as
all ANSI C compilers still support K&R style).

cheers,
