Tom Tromey 4176f14d9c Don't check HAVE_UNISTD_H ... I noticed some spots that were checking HAVE_UNISTD_H. There is no need to do this, as <unistd.h> is unconditionally included in many places in gdb. This sort of cleanup was done once before, in 2013: 2013-07-01 Pedro Alves <palves@redhat.com> * defs.h: Don't check HAVE_UNISTD_H before including <unistd.h>. (STDIN_FILENO, STDOUT_FILENO, STDERR_FILENO): Delete. * tracepoint.c: Don't check HAVE_UNISTD_H before including <unistd.h>. HAVE_UNISTD_H seems to come from gnulib, so there are still mentions of it in the source. gdb/ChangeLog 2018-10-01 Tom Tromey <tom@tromey.com> * unittests/scoped_mmap-selftests.c: Don't check HAVE_UNISTD_H. * unittests/scoped_fd-selftests.c: Don't check HAVE_UNISTD_H. * common/scoped_fd.h: Don't check HAVE_UNISTD_H.		2018-10-01 02:58:23 -06:00
