Converting from free-form macros to an enum gives a bit of type-safety. This caught places where we would assign host error numbers to what should contain a target fileio error number, for instance in target_fileio_pread. I added the FILEIO_SUCCESS enumerator, because remote.c:remote_hostio_parse_result initializes the remote_errno output variable to 0. It seems better to have an explicit enumerator than to assign a value for which there is no enumerator. I considered initializing this variable to FILEIO_EUNKNOWN instead, such that if the remote side replies with an error and omits the errno value, we'll get an errno that represents an error instead of 0 (which reprensents no error). But it's not clear what the consequences of that change would be, so I prefer to err on the side of caution and just keep the existing behavior (there is no intended change in behavior with this patch). Note that remote_hostio_parse_resul still reads blindly what the remote side sends as a target errno into this variable, so we can still end up with a nonsensical value here. It's not good, but out of the scope of this patch. Convert host_to_fileio_error and fileio_errno_to_host to return / accept a fileio_error instead of an int, and cascade the change in the whole chain that uses that.

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.
