[uClibc-cvs] uClibc/libc/stdlib Makefile, 1.51, 1.52 stdlib.c, 1.10, 1.11 strtod.c, 1.6, 1.7

[Manuel Novoa III]

Update of /var/cvs/uClibc/libc/stdlib
In directory winder:/tmp/cvs-serv28208/libc/stdlib

Modified Files:
	Makefile stdlib.c strtod.c 
Log Message:
Add a new *scanf implementation, includeing the *wscanf functions.
  Should be standards compliant and with several optional features,
  including support for hexadecimal float notation, locale awareness,
  glibc-like locale-specific digit grouping with the `'' flag, and
  positional arg support.  I tested it pretty well (finding several
  bugs in glibc's scanf in the process), but it is brand new so be
  aware.

The *wprintf functions now support floating point output.  Also, a
  couple of bugs were squashed.  Finally, %a/%A conversions are
  now implemented.

Implement the glibc xlocale interface for thread-specific locale
  support.  Also add the various *_l(args, locale_t loc_arg) funcs.

  NOTE!!!  setlocale() is NOT threadsafe!  NOTE!!!

The strto{floating point} conversion functions are now locale aware.
  The also now support hexadecimal floating point notation.

Add the wcsto{floating point} conversion functions.

Fix a bug in mktime() related to dst.  Note that unlike glibc's mktime,
  uClibc's version always normalizes the struct tm before attempting
  to determine the correct dst setting if tm_isdst == -1 on entry.

Add a stub version of the libintl functions.  (untested)

Fixed a known memory leak in setlocale() related to the collation data.

Add lots of new config options (which Erik agreed to sort out :-),
  including finally exposing some of the stripped down stdio configs.
  Be careful with those though, as they haven't been tested in a
  long time.


(temporary) GOTCHAs...

The ctype functions are currently incorrect for 8-bit locales.  They
  will be fixed shortly.

The ctype functions are now table-based, resulting in larger staticly
  linked binaries.  I'll be adding an option to use the old approach
  in the stub locale configuration.

+ * The primary objective of this implementation was minimal size and
+ * portablility, while providing robustness and resonable accuracy.
  *
  * This implementation depends on IEEE floating point behavior and expects
  * to be able to generate +/- infinity as a result.
  *
  * There are a number of compile-time options below.
+ */
+
+/* July 27, 2003
+ *
+ * General cleanup and some minor size optimizations.
+ * Change implementation to support __strtofpmax() rather than strtod().
+ *   Now all the strto{floating pt}() funcs are implemented in terms of
+ *   of the internal __strtofpmax() function.
+ * Support "nan", "inf", and "infinity" strings (case-insensitive).
+ * Support hexadecimal floating point notation.
+ * Support wchar variants.
+ * Support xlocale variants.
+ *
+ * TODO:
  *
+ * Consider accumulating blocks of digits in longs to save floating pt mults.
+ *   This would likely be much better on anything that only supported floats
+ *   where DECIMAL_DIG == 9.  Actually, if floats have FLT_MAX_10_EXP == 38,
+ *   we could calculate almost all the exponent multipliers (p_base) in
+ *   long arithmetic as well.
