Quoting the FAQ at http://gcc.gnu.org/wiki/NewWconversion#faq
Why Wconversion is not enabled by -Wall or at least by -Wextra?
Implicit conversions are very common in C. This tied with the fact that there
is no data-flow in front-ends (see next question) results in hard to avoid
warnings for perfectly working and valid code. Wconversion is designed for a
niche of uses (security audits, porting 32 bit code to 64 bit, etc.) where the
programmer is willing to accept and workaround invalid warnings. Therefore, it
shouldn't be enabled if it is not explicitly requested.
