	* sysdeps/wordsize-32/stdint.h (INT8_C, INT16_C, INT32_C, INT64_C,
	UINT8_C, UINT16_C, UINT32_C, UINT64_C): Remove casts, they must be
	integer constants.  Use ## directly instead of __CONCAT so that
	the suffix string is not expanded as a macro.
	* sysdeps/wordsize-64/stdint.h (INT8_C, INT16_C, INT32_C, INT64_C,
	UINT8_C, UINT16_C, UINT32_C, UINT64_C): Likewise.
	(INT64_MIN, INT64_MAX, UINT64_MAX, INT_LEAST64_MIN,
	INT_LEAST64_MAX, UINT_LEAST64_MAX, INT_FAST16_MIN, INT_FAST32_MIN,
	INT_FAST64_MIN, INT_FAST16_MAX, INT_FAST32_MAX, INT_FAST64_MAX,
	UINT_FAST16_MAX, UINT_FAST32_MAX, UINT_FAST64_MAX, INTMAX_MIN,
	INTMAX_MAX, UINTMAX_MAX): Define as long constants, not long long.

1999-01-28  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* locale/mb_cur_max.c (__ctype_get_mb_cur_max): Correct return
	type to size_t.
	* locale/broken_cur_max.c (__ctype_get_mb_cur_max): Likewise.
	* stdlib/stdlib.h (__ctype_get_mb_cur_max): Likewise.

/* This is a gross hack to get broken programs running.
ISO C provides no mean to find out how many bytes the wide
character representation really uses. But it defines MB_CUR_LEN to
return the information for the multi-byte character representation.
Many programmers don't know the difference between the two and
think this means the same. But assuming all characters have a size
of MB_CUR_LEN after they have been processed by `mbrtowc' is wrong.
Instead the maximum number of characters used for the conversion is
MB_CUR_LEN.
It is known that some Motif applications have this problem. To
cure this one has to make sure the glibc uses the function in this
file instead of the one in locale/mb_cur_max.c. This can either be
done by linking with this file or by using the LD_PRELOAD feature
of the dynamic linker. */
