Please CC [EMAIL PROTECTED] on replies. Log of report can be found at http://bugs.debian.org/128950 ] 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). >How-To-Repeat: >Fix:
