With -Wconversion you get
t.c:5: warning: passing argument 1 of toLongLong with different width due to
prototype
though -Wconversion is neither in -Wall nor -Wextra. I see you filed against
C++, which doesn't warn here, but we have a bug for a similar case already.
Also the C diagnostic could be improved in the case of a widening sign
conversion,
because that is more likely an error than a non-widening sign conversion.
