* (AC_FUNC_MEMCHR): Remove. Autoconf didn't adopt this, since we need notPaul Eggert1994-09-131-4/+5
| | | | | | | | worry about an old experimental library where memchr didn't work. (AC_FUNC_MEMCMP): Not needed, since we only test for equality. (AC_REPLACE_FUNCS): Add test for memchr. (AC_CHECK_FUNCS): Check for memchr, not memcpy, since it'll be cached. (AC_CHECK_HEADERS): Add string.h; regex.c uses on some old hosts.
* (memcmp): Define in terms of bcmp.Paul Eggert1994-09-131-2/+3
| | | | Use HAVE_MEMCHR to test for all mem* routines.
* (srcs): Remove memcmp.c. We use bcmp if memcmp doesn't work, sincePaul Eggert1994-09-131-3/+4
| | | | we only test for equality.
* (line_cmp): Now takes just two arguments, and no longer optimizesPaul Eggert1994-09-121-37/+45
| | | | | | | for common case of exact equality; the caller does that optimization now. Optimize for the common case of mostly exact equality. Use isupper/tolower instead of islower/toupper, for consistency. (line_cmp, print_line): Use '\n' instead of line_end_char.
* Use more modern autoconf approach to standard C headers.Paul Eggert1994-09-121-24/+17

* Fix copyright notice.Paul Eggert1994-09-126-8/+8
|
* (binary_file_p): Assume non-broken memchr.Paul Eggert1994-09-121-30/+49
| | | | | | | | | | (find_and_hash_each_line): Revamp to fix some inconsistencies with -b -w -i and incomplete lines. Incomplete lines are now put into their own bucket. This means line_cmp no longer needs line length arguments, and equivalence classes' line length no longer need to include \n. Invoke line_cmp only if memcmp fails and if ignore_some_line_changes. (prepare_text_end): -B no lonter ignores missing newlines. (read_files): Allocate another bucket for incomplete lines.
* (ignore_some_line_changes): New variable; replaces `length_varies'.Paul Eggert1994-09-121-6/+3
| | | | | (line_end_char): Removed; it wasn't being used consistently. (line_cmp): Now takes just pointers to two lines.
* (main): Use '\n', not line_end_char.Paul Eggert1994-09-121-4/+4
| | | | (ignore_some_line_changes): New variable; replaces `length_varies'.
