FWIW, I took a quick look at this but gave up. For toupper and tolower, I thought I could just make them aliases to CORE::uc and CORE::lc, but I discovered you can't do that in Perl, and I'm not up to figuring out the XS method. For strerror, I discovered that it already "works", but only because locale is not properly lexically scoped. That is, there are many places where perl must call locale-aware C functions (like strerror()), but perl doesn't turn on and off C locale support (with setlocale()) by locale scope. (I infer from this that nobody's interested in getting locale support 100% right anyway.) AndrewThread Previous | Thread Next
