I was puzzled at first as well - and personally I think that this
warning is truly bad. It's supposed to detect the unprototyped use of
malloc() (so malloc is implicitly supposed to return int, but then cast
to a pointer). But -Wimplicit-function-declaration (included in -Wall)
should be good enough in that scenario.
