Suggested by Eric Blake in <https://lists.gnu.org/archive/html/bug-gnulib/2023-03/msg00060.html>. * lib/printf-parse.c (PRINTF_PARSE): Recognize the 'B' conversion. * lib/printf-parse.h: Update comments. * lib/wprintf-parse.h: Likewise. * lib/vasnprintf.c (MAX_ROOM_NEEDED): Treat the 'B' conversion like 'b'. (VASNPRINTF): Implement 'B' conversion if NEED_PRINTF_DIRECTIVE_UPPERCASE_B is set. Support the 'B' conversion if requested. * m4/printf.m4 (gl_PRINTF_DIRECTIVE_B): When cross-compiling, guess yes on glibc >= 2.35. (gl_PRINTF_DIRECTIVE_UPPERCASE_B): New macro. * m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS): Renamed from gl_PREREQ_VASNPRINTF_WITH_EXTRAS. (gl_PREREQ_VASNPRINTF_DIRECTIVE_UPPERCASE_B, gl_PREREQ_VASNPRINTF_WITH_GNU_EXTRAS): New macros. * m4/vasnprintf-posix.m4 (gl_FUNC_VASNPRINTF_IS_POSIX): New macro, extracted from gl_FUNC_VASNPRINTF_POSIX. (gl_FUNC_VASNPRINTF_POSIX): Require it. Invoke gl_PREREQ_VASNPRINTF_WITH_POSIX_EXTRAS. * m4/vasnprintf-gnu.m4: New file. * modules/vasnprintf-gnu: New file. * modules/c-vasnprintf (configure.ac): Update. * modules/unistdio/u8-vasnprintf (configure.ac): Likewise. * modules/unistdio/u8-u8-vasnprintf (configure.ac): Likewise. * modules/unistdio/u16-vasnprintf (configure.ac): Likewise. * modules/unistdio/u16-u16-vasnprintf (configure.ac): Likewise. * modules/unistdio/u32-vasnprintf (configure.ac): Likewise. * modules/unistdio/u32-u32-vasnprintf (configure.ac): Likewise. * modules/unistdio/ulc-vasnprintf (configure.ac): Likewise.
