Update. 1999-06-18 Thorsten Kukuk <kukuk@suse.de> * sysdeps/alpha/atomicity.h: Correct counting of subsections. 1999-06-17 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * stdlib/tst-strtoll.c: Avoid warning about huge constant. 1999-06-20 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * stdio-common/vfprintf.c (group_member): Make parameters and return types pointers to CHAR_T instead of UCHAR_T. (vfprintf): Change type of work_buffer, workend and string to CHAR_T pointer/array. (process_arg, process_string_arg): Adjust/remove casts. Add missing use of L_ macro. (printf_unknown): Add missing uses of L_ macro. 1999-06-20 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * wcsmbs/wcschrnul.c: Explicitly cast return value to avoid warning. 1999-06-20 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * libio/wgenops.c (__wuflow): Fix use of WEOF vs. EOF. Call _IO_switch_to_wget_mode instead of _IO_switch_to_get_mode. (__wunderflow): Likewise. (_IO_switch_to_wget_mode): Likewise. (_IO_init_wmarker): Likewise. * libio/wfileops.c (_IO_wfile_seekoff): Call _IO_switch_to_wget_mode, not _IO_switch_to_get_mode. (_IO_wfile_jumps): Fix pbackfail entry. * libio/iosetvbuf.c (_IO_setvbuf): Only call wide char setbuf function if the stream is currently unoriented. 1999-06-19 Zack Weinberg <zack@rabi.columbia.edu> * wcsmbs/wchar.h: Define __need___va_list before including stdarg.h. Wrap all wide stream functions with #ifdef __USE_ISOC9X. Use __gnuc_va_list in v*w(printf|scanf) prototypes. 1999-06-20 Andreas Jaeger <aj@arthur.rhein-neckar.de> * libio/oldiopopen.c (_IO_old_proc_open): Apply change from 1999-03-29 to iopopen also here. Reported by Richard Braakman <dark@xs4all.nl>. 1999-06-20 Andreas Jaeger <aj@arthur.rhein-neckar.de> * include/features.h: Use __GNUC_PREREQ. * sysdeps/i386/fpu/bits/mathinline.h: Likewise 1999-06-19 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * stdio-common/vfscanf.c (ungetc, inchar) [COMPILE_WPRINTF]: Change EOF to WEOF and remove cast. (UNGETC): Remove macro. (_IO_vfwscanf): Change isspace to ISSPACE and UNGETC to ungetc. * stdio-common/printf-parse.h (find_spec) [!COMPILE_WPRINTF]: Change ISASCII to isascii and MBRLEN to mbrlen. (parse_one_spec): Compare info.spec always against wchar_t values. * stdio-common/vfprintf.c: Remove unused ISASCII and MBRLEN. (_itoa, _itoa_word) [COMPILE_WRPINTF]: Don't cast second argument. (NOT_IN_JUMP_RANGE, CHAR_CLASS): Change (int) to (INT_T), use L_. 1999-06-19 Andreas Schwab <schwab@issan.cs.uni-dortmund.de> * libio/Makefile (shared-only-routines): Add oldiofgetpos, oldiofgetpos64, oldiofsetpos and oldiofsetpos64. (routines): Include oldiofgetpos, oldiofgetpos64, oldiofsetpos and oldiofsetpos64 only if doing versioning.
