Sparse issues many "Using plain integer as NULL pointer" warnings while checking nedmalloc.c (at least 98 such warnings before giving up due to "too many warnings"). In addition, sparse issues some "non-ANSI function declaration" type warnings for the symbols 'win32_getcurrentthreadid', 'malloc_stats' and 'malloc_footprint'.
In order to suppress the NULL pointer warnings, rather than replace all uses of '0' as a null pointer representation with NULL, we add -Wno-non-pointer-null to SPARSE_FLAGS while checking nedmalloc.c.
In order to suppress the "non-ANSI function declaration" warnings, we simply include the missing 'empty parameter list' prototype (void) in the function declarations.
