One addition, arising from \[http://issues.apache.org/SpamAssassin/show_bug.cgi?id=4593 bug 4593\]: if there are warnings about variables being signed/unsigned, caused by use of "int" types in system calls that accept "size_t" (or similar), it is better to \*carefully\* perform a cast in the call(s) to the specific system calls being warned about, instead of changing the type of variables on a global scale to be a "size_t". Bug 4593 is a good example of how this can cause bugs as a side-effect due to -1 being used as an error indicator. |
