From: Pedro Alves Date: Mon, 1 Jul 2013 11:19:27 +0000 (+0000) Subject: Rely on gnulib's unistd.h replacement. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=bc7dea8de974648cd4e38d154abcca6879e630cc;p=binutils-gdb.git Rely on gnulib's unistd.h replacement. With gnulib's unistd module, we can assume unistd.h is always present, and that STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO are always defined. Don't remove unistd.h from GDB's configure.ac, as later tests in the file use HAVE_UNISTD_H checks. gdb/ 2013-07-01 Pedro Alves * defs.h: Don't check HAVE_UNISTD_H before including .
