Indeed. dmd should warn about any incompatible data passed as
variadic parameters. It's simple to decide: only fundamental
types that correspond to C counterparts should be allowed.
Hmmm... Even that's not that simple: int is 32 bits in D but
unspecified in C.
Maybe printf should not be visible at all - or under a different
name ("cprintf" or something similar). It's just too tempting...
C variadic arguments are one of the most unsafe features of the C
language. A total mess.
