2026-05-26Update from Gnulib by running admin/merge-gnulibPaul Eggert
In addition to the automatic changes, also do the following, needed due to recent Gnulib changes. * admin/merge-gnulib (AVOIDED_MODULES): Add btoc32, c32_apply_type_test, c32_get_type_test, c32isalnum, c32rtomb, c32tolower, c32toupper, localeinfo, mbrtoc32-regular. Remove btowc, iswctype, mbrtowc, wcrtomb, wctype, wctype-h. Also remove iswblank, iswdigit, iswxdigit, locale-h, raise, stdarg-h, some of which perhaps could have been removed earlier. * configure.ac (_REGEX_AVOID_UCHAR_H): New macro.

2024-05-18Prefer stdbit.h to count-one-bits.h etcPaul Eggert
C23's <stdbit.h> in the long run should be better supported than Gnulib's count-one-bits.h and similar headers, so switch to the C23 primitives, with a Gnulib fallback for platforms lacking C23. * admin/merge-gnulib (GNULIB_MODULES): Remove count-leading-zeros, count-one-bits, count-trailing-zeros. Add stdc_bit_width, stdc_count_ones, stdc_trailing_zeros. * lib/count-leading-zeros.c, lib/count-leading-zeros.h: * lib/count-one-bits.c, lib/count-one-bits.h: * lib/count-trailing-zeros.c, lib/count-trailing-zeros.h: Remove. * lib/stdbit.c, lib/stdbit.in.h, lib/stdc_bit_width.c: * lib/stdc_count_ones.c, lib/stdc_leading_zeros.c: * lib/stdc_trailing_zeros.c, m4/stdbit_h.m4: New files, copied from Gnulib. * lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate. * src/data.c: Do not include count-one-bits.h, count-trailing-zeros.h. Instead, rely on lisp.h including stdbit.h. (Flogcount, Fbool_vector_count_population) (Fbool_vector_count_consecutive): Use stdbit.h macros instead of count-one-bits.h and count-trailing-zeros.h macros. (shift_right_ull, count_one_bits_word, pre_value) (count_trailing_zero_bits): Remove; no longer needed. * src/lisp.h: Include stdbit.h instead of count-leading-zeros.h. (elogb): Use stdbit.h macro instead of count-leading-zeros.h macro.
