strftime: import from gnulib
* Makefile.in (GNULIB_MODULES): Add strftime.
* configure.in (AC_FUNC_STRFTIME, my_strftime): Remove; no longer
needed.
* aclocal.m4, configure, lib/Makefile.in, lib/gnulib.mk, m4/gl-comp.m4:
Regenerate.
* lib/strftime.c, lib/strftime.h, lib/stdbool.in.h: New files,
imported from gnulib.
* m4/strftime.m4, m4/stdbool.m4, m4/tm_gmtoff.m4: Likewise.
This incorporates many changes from gnulib, including simpler
handling of multibyte formats, porting to mingw32 and other
platforms, and support for higher-resolution time stamps.
Emacs does not yet use the higher-resolution interface.

#ifndef _GL_STDBOOL_H
#define _GL_STDBOOL_H
/* ISO C 99 <stdbool.h> for platforms that lack it. */
/* Usage suggestions:
Programs that use <stdbool.h> should be aware of some limitations
and standards compliance issues.
Standards compliance:
- <stdbool.h> must be #included before 'bool', 'false', 'true'
can be used.
- You cannot assume that sizeof (bool) == 1.
- Programs should not undefine the macros bool, true, and false,
as C99 lists that as an "obsolescent feature".
Limitations of this substitute, when used in a C89 environment:
- <stdbool.h> must be #included before the '_Bool' type can be used.
- You cannot assume that _Bool is a typedef; it might be a macro.
- Bit-fields of type 'bool' are not supported. Portable code
should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
- In C99, casts and automatic conversions to '_Bool' or 'bool' are
performed in such a way that every nonzero value gets converted
to 'true', and zero gets converted to 'false'. This doesn't work
with this substitute. With this substitute, only the values 0 and 1
give the expected result when converted to _Bool' or 'bool'.
- C99 allows the use of (_Bool)0.0 in constant expressions, but
this substitute cannot always provide this property.
Also, it is suggested that programs use 'bool' rather than '_Bool';
this isn't required, but 'bool' is more common. */

definitions below, but temporarily we have to #undef them. */
#if defined __BEOS__ && !defined __HAIKU__
# include <OS.h> /* defines bool but not _Bool */
# undef false
# undef true
#endif
/* For the sake of symbolic names in gdb, we define true and false as
enum constants, not only as macros.
It is tempting to write
typedef enum { false = 0, true = 1 } _Bool;
so that gdb prints values of type 'bool' symbolically. But if we do
this, values of type '_Bool' may promote to 'int' or 'unsigned int'
(see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'
(see ISO C 99 6.3.1.1.(2)). So we add a negative value to the
enum; this ensures that '_Bool' promotes to 'int'. */
#if defined __cplusplus || (defined __BEOS__ && !defined __HAIKU__)
/* A compiler known to have 'bool'. */
/* If the compiler already has both 'bool' and '_Bool', we can assume they
are the same types. */

/* If @HAVE__BOOL@:
Some HP-UX cc and AIX IBM C compiler versions have compiler bugs when
the built-in _Bool type is used. See

http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html
Similar bugs are likely with other compilers as well; this file
wouldn't be used if <stdbool.h> was working.
So we override the _Bool type.
If !@HAVE__BOOL@:
Need to define _Bool ourselves. As 'signed char' or as an enum type?
Use of a typedef, with SunPRO C, leads to a stupid
"warning: _Bool is a keyword in ISO C99".
Use of an enum type, with IRIX cc, leads to a stupid
"warning(1185): enumerated type mixed with another type".
Even the existence of an enum type, without a typedef,
"Invalid enumerator. (badenum)" with HP-UX cc on Tru64.
The only benefit of the enum, debuggability, is not important
with these compilers. So use 'signed char' and no enum. */
