load of _l suffixed versions of various standard library functions that use
the global locale, making them take an explicit locale parameter. Also
adds support for per-thread locales. This work was funded by the FreeBSD
Foundation.
Please test any code you have that uses the C standard locale functions!

really so.
"If the value of base is 16, the characters 0x or 0X may optionally
precede the sequence of letters and digits, following the sign if
present."

definitions of the functions that convert strings to numbers
and are defined by IEEE Std 1003-1.2001.
- Use ANSI-C function definitions for all of the functions
mentioned above plus strtouq and strtoq.
- Update the prototypes in the manual pages.
The definition of character class digit requires that only ten characters
-the ones defining digits- can be specified; alternate digits (for
example, Hindi or Kanji) cannot be specified here. However, the encoding
may vary if an implementation supports more than one encoding.
The definition of character class xdigit requires that the characters
included in character class digit are included here also and allows for
different symbols for the hexadecimal digits 10 through 15.
'locale not used' statement from comments and BUGS section of manpage.
strtol(): fix non-portable 'cutoff' calculation using the same method as
in strtoll().
Cleanup 'cutoff' calculation, remove unneded casts. Misc. cleanup to
make all functions looks the same.
Implement EINVAL reaction per POSIX, document it in manpage, corresponding
POSIX example quotes here:
------------------------------------------------
If the subject sequence is empty or does not have the expected form, no
conversion is performed; the value of str is stored in the object pointed
to by endptr, provided that endptr is not a null pointer.
If no conversion could be performed, 0 shall be returned and errno may be
set to [EINVAL].
[EINVAL] The value of base is not supported.
Since 0, {LONG_MIN} or {LLONG_MIN}, and {LONG_MAX} or {LLONG_MAX} are
returned on error and are also valid returns on success, an application
wishing to check for error situations should set errno to 0, then call
strtol( ) or strtoll ( ), then check errno.
-----------------------------------------------------
like 38400<any 8bit char, isalpha> it not detect this stuff and
produce very big number instead. Fixed by operating with unsigned char
and checking for isascii. (secure/telnetd hits by it f.e.)
