A few files were missing headers for memset/malloc, likely missed
because the files don't directly call the functions, rather they
come in via macros in libc/include/sys/reent.h:
#define _REENT_CHECK(var, what, type, size, init) do { \
struct _reent *_r = (var); \
if (_r->what == NULL) { \
_r->what = (type)malloc(size); \
#define _REENT_CHECK_ASCTIME_BUF(var) \
_REENT_CHECK(var, _asctime_buf, char *, _REENT_ASCTIME_SIZE, \
memset((var)->_asctime_buf, 0, _REENT_ASCTIME_SIZE))
Without these fixes, implicit function signatures are provided,
which gcc warns could cause aliasing issues down the line:
