+        Clean up errno reporting and fix some errno-reporting bugs.
+        * callproc.c (Fcall_process):
+        * fileio.c (Fcopy_file, Finsert_file_contents, Fwrite_region):
+        * process.c (create_process, Fmake_network_process):
+        * unexaix.c (report_error):
+        * unexcoff.c (report_error):
+        Be more careful about reporting the errno of failed operations.
+        The code previously reported the wrong errno sometimes.
+        Also, prefer report_file_errno to setting errno + report_file_error.
+        (Fcall_process): Look at openp return value rather than at path,
+        as that's a bit faster and clearer when there's a numeric predicate.
+        * fileio.c (report_file_errno): New function, with most of the
+        old contents of report_file_error.
+        (report_file_error): Use it.
+        (Ffile_exists_p, Ffile_accessible_directory_p):
+        Set errno to 0 when it is junk.
+        * fileio.c (Faccess_file):
+        * image.c (x_create_bitmap_from_file):
+        Use faccessat rather than opening the file, to avoid the hassle of
+        having a file descriptor open.
+        * lisp.h (report_file_errno): New decl.
+        * lread.c (Flocate_file_internal): File descriptor 0 is valid, too.
+
         Minor EBADF fixes.
         * process.c (create_process, wait_reading_process_output) [AIX]:
         Remove obsolete SIGHUP-related  code, as Emacs no longer disables
