ftello: Work around bug in macOS >= 10.15.
Reported by Martin Storsjö <martin@martin.st> in <https://lists.gnu.org/archive/html/bug-gnulib/2020-12/msg00002.html>. * m4/ungetc.m4 (gl_FUNC_UNGETC_WORKS): On macOS, don't define FUNC_UNGETC_BROKEN. Instead, set gl_ftello_broken_after_ungetc to yes. * m4/ftello.m4 (gl_FUNC_FTELLO): Invoke gl_FUNC_UNGETC_WORKS, and arrange to provide the workaround if ftello is broken after ungetc. * lib/ftello.c: Include <errno.h>, intprops.h. (ftello) [FTELLO_BROKEN_AFTER_UNGETC]: Implement from scratch. * modules/ftello (Files): Add m4/ungetc.m4. (Depends-on): Add intprops. * doc/posix-functions/ftello.texi: Mention the macOS bug.
