            Bug ID: 275831
           Summary: wcstoimax function is missing 'L' qualifier on a
                    character constant
           Product: Base System
           Version: Unspecified
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: misc
          Assignee: bugs@FreeBSD.org
          Reporter: Paul.Green@stratus.com

Please compare lib/libc/locale/wcstoimax.c to lib/libc/locale/wcstoumax.c and
you will see that the former file uses the expression:

else if (c >= 'a' && c <= 'z')

while the latter file uses the expression:

else if (c >= L'a' && c <= L'z')

The latter expression is correct.

This expression ensures that wide character input strings presented to
wcstoimax are limited to the characters 0-9, A-Z, and a-z. This bug is present
in the initial version of the source file from 2002.
