[Bug c/42885] New: -fmudflap prevents 'conflicting types' warning

["christophe dot lyon at st dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Considering the sample code:
int round(int i) { return i;}
Compiled with gcc 4.4.3:
$ gcc -Wall round.c -c
round.c:1: warning: conflicting types for built-in function 'round'

If I add the -fmudflap option, the warning disappears:
$ gcc -Wall round.c -c -fmudflap
$

I guess it should still warn.
