I think sparse issues a spurious warning about "static" for this program.
Right?
Morten
static void foo (int);
void foo (int a) { }
welinder@anemone:~> cgcc -Wall -c sss.c
sss.c:2:6: warning: symbol 'foo' was not declared. Should it be static?
sss.c:2: warning: ‘foo’ defined but not used

The second warning comes from gcc, I think. But yes, the first warning
represents a long-standing sparse bug; "static" in the prototype doesn't
propagate to the definition.
