Update.
1999-01-28 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * 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. 1999-01-27 Philip Blundell <pb@nexus.co.uk> * sysdeps/unix/sysv/linux/arm/vfork.S: Deleted.
