commit f5eee5c72b2ab56f3faf4f46729fe82805efde68
Author: Joseph Myers <joseph@codesourcery.com>

    Fix strtol in Turkish locales (bug 19242).
    
    The implementations of strtol and related functions use
    locale-specific conversions to upper case before determining whether a
    character is a valid letter in the argument.  This means that in
    Turkish locales such as tr_TR.UTF-8 and tr_TR.ISO-8859-9, "i" is
    interpreted as not being a valid number, when if the base passed to
    strtol is 19 or more it should be interpreted as the number 18.
    
    ISO C explicitly says "The letters from a (or A) through z (or Z) are
    ascribed the values 10 through 35", so clearly intends the standard
    ASCII letters (otherwise you wouldn't generally have exactly 26
    letters to ascribe such values) (whereas white-space must be
    identified according to the locale).  In particular, 'i' and 'I' must
    be understood to be in that sequence.
    
    This patch makes the code do the case conversions and classification
    in the C locale; the user's locale remains used for whitespace testing
    (explicitly correct according to ISO C).  Note that the way the code
    worked, the only non-ASCII letter that would previously have been
    accepted would have been the Turkish 'ı' (dotless 'i'), because the
    uppercase version of that in Turkish locales is 'I'.  This patch means
    that will no longer be accepted, which seems appropriate.
    
    Tested for x86_64 and x86.
