Package: gcc-3.0
Version: 1:3.0.3-1
Severity: normal
The -Wconversion option to gcc is documented as doing two things:
------------------------------------------------------------------------
`-Wconversion'
Warn if a prototype causes a type conversion that is different
from what would happen to the same argument in the absence of a
prototype. This includes conversions of fixed point to floating
and vice versa, and conversions changing the width or signedness
of a fixed point argument except when the same as the default
promotion.
Also, warn if a negative integer constant expression is implicitly
converted to an unsigned type. For example, warn about the
assignment `x = -1' if `x' is unsigned. But do not warn about
explicit casts like `(unsigned) -1'.
------------------------------------------------------------------------
It'd be nice if these two behaviors were two controlled via two
separate flags. The second behavior would have caught a bug I've been
hunting for hours, while the first behavior is very undesirable to me
(and useless since I also compile with -Wstrict-prototypes).
