------- Comment #4 from manu at gcc dot gnu dot org 2006-11-26 13:57 -------
This will be fixed by the new Wconversion option. Actually, it has been fixed
already for gcc version 4.3.0 20061124 (experimental).
manuel@gcc05:~$ local/bin/g++ -c -Wconversion pr18821.C
pr18821.C: In function int main():
pr18821.C:8: warning: conversion to short unsigned int from long unsigned
int may alter its value
I hope this makes you happy!
It is a shame that I missed this bug in the Changelog. Should I modify the
Changelog or what is done is done ?
