/usr/include/signal.h:101: error: shadowed declaration is here
tests/bp_signal.c: In function ‘bp_event’:
tests/bp_signal.c:144: error: declaration of ‘signal’ shadows a global declaration
/usr/include/signal.h:101: error: shadowed declaration is here
tests/bp_signal.c: In function ‘wp_event’:
tests/bp_signal.c:149: error: declaration of ‘signal’ shadows a global declaration
/usr/include/signal.h:101: error: shadowed declaration is here
