The GCC documentation says: -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. In your program, in the absence of prototype, d would be promoted to int, thus the warning is correct. Wconversion is only useful for translating very old C code to ANSI/ISO C. Since this behaviour is not very useful in the present day, and Wconversion also warns for unsigned i = -1, we are going to move the above behaviour to Wtraditional-conversion and make Wconversion warn for implicit conversions that may change a value. This is planned for GCC 4.3 . For more info, please check http://gcc.gnu.org/wiki/Wcoercion and don't hesitate to contact me. (That wiki page is work in progress, not definitive, actually, it is a bit outdated). Testing and comments are welcome. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29739 ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
