Hi Segher, > The problem here is, that -Wconversion does _not_ warn about type conversions in your code! From: http://gcc.gnu.org/onlinedocs/gcc-4.0.2/gcc/Warning-Options.html ------------------------------------------------------------------- -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. ------------------------------------------------------------------- What kind of type conversions in your code are you referring to? --Eljay
