No, don't file a bug report. this is documented behavior for the Vax C
compiler (which obviously isn't fully ansi-compatible yet).

try cc /standard=portable instead. that will warn about pointers to
incorrect types, or different levels of indirection (like char * vs.
char **), plus a number of other warnings that are not reported by
default.
