now fixed on plan 9:

% cat x.c
#pragma lib "libc.a"

extern int qsort[];
extern int print(char*, ...);

void
main(void)
{
	int i;

	for(i=0; i<10; i++)
		print("%08ux\n", qsort[i]);
}
% 8c -T x.c
% 8l x.8
qsorts: incompatible type signatures b3a1d3d5(x.8) and
c7dcac09(/386/lib/libc.a(qsort)) for qsort
