*int _Strcoll() - Collate locale strings
*
*Purpose:
* Compare two strings using the locale LC_COLLATE information.
* [ANSI].
*
* Non-C locale support available under _INTL switch.
* In the C locale, strcoll() simply resolves to strcmp().
*Entry:
* const char *s1b = pointer to beginning of the first string
* const char *s1e = pointer past end of the first string
* const char *s2b = pointer to beginning of the second string
* const char *s1e = pointer past end of the second string
* const _Collvec *ploc = pointer to locale info
*
*Exit:
* Less than 0 = first string less than second string
* 0 = strings are equal
* Greater than 0 = first string greater than second string
*
*Exceptions:
* _NLSCMPERROR = error
* errno = EINVAL
*
