Commit c1023ee353705671aa9a8e4e1179022277add2aa changed the way path_conv::binmode() works. Rather than returning three states, O_BINARY, O_TEXT, 0, it only returned 2 states, O_BINARY, O_TEXT. Since mounts are only binary if they are explicitely mounted binary by setting the MOUNT_BINARY flag, textmode is default. This introduced a new bug. When inheriting stdio HANDLEs from native Windows processes, the fhandler and its path_conv are created from a device struct only. None of the path or mount flags get set this way. So the mount flags are 0 and path_conv::binmode() returned 0. After the path_conv::binmode() change it returned O_TEXT since, as explained above, the default mount mode is textmode. Rather than just enforcing binary mode for path_conv's created from device structs, this patch changes the default mount mode to binary: Replace MOUNT_BINARY flag with MOUNT_TEXT flag with opposite meaning. Drop all explicit setting of MOUNT_BINARY. Drop local set_flags function, it doesn't add any value. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
