I really doubt any compilers will warn on void* casts in pure C. Usually the warning is if you do: int *x; char *y = x; or similar. But if x was "void*"

I really doubt any compilers will warn on void* casts in pure C. Usually the warning is if you do: int *x; char *y = x; or similar. But if x was "void*", it really should work on all C compilers.
