             Bug #: 14910
           Summary: Need a portable implementation of
                    llvm::sys::locale::columnWidth
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Support Libraries
        AssignedTo: unassignedbugs at nondot.org

Currently there is a proper implementation of columnWidth for Mac OS X, but
only a stub implementation for other OSes.

The Mac OS X implementation (lib/Support/LocaleXlocale.inc) is currently not
portable because it uses *_l functions (e.g., mbstowcs_l) that are like their
standard counterparts (mbstowcs_l), but take a locale as an explicit parameter.
 This implementation can be made portable by using standard functions and
assuming that we have a UTF-8 locale.

Is this viable?
