FYI, this quoting is correct according to the GDB manual...
That's right, this rings a bell :-).  I think the best place to handle this escaping of back slashes would be in the MIBreakInsert constructor, and in any other constructor that deals with file paths.

-gdb-set sysroot C:\Program\CodeSourcery\SourceryG++\arm-none-linux-gnueabi\libc
... and this is correct in practice, but wrong according to the
manual.  It's a known bug in GDB that we quote different MI commands
differently, and I hope we'll fix it eventually.
Thus the reason why GDB-CDI uses a command factory instead of command constructors directly.  In DSF we did away with the command factory, so our debugger will be only compatible with the latest version of the MI protocol.  To support older versions of GDB we will need customized services which use old versions of commands.

  1. It looks loke the gdb MI interface for CodeSourcery accepts inserting breakpoints using backslash
GCC puts whatever was on its command line into the ELF file, and GDB
reads it from there.  So it depends which slashes your builder uses,
whether you have a mingw32 or cygwin GCC, et cetera.
Hopefully we can handle these differences using appropriate source containers.  If that's not enough, we'll need customized GDB-DSF services for these different GDB variants.  This is OK, this is how DSF debuggers are meant to be extended.

  2. There's a file and a fullname attribute in the response for the -break-insert command, possibly useful for source lookup.
Yes indeed.
I'm not sure output to -break-insert will be that useful, since to insert a breakpoint we need to know the correct path in the first place.  But I assume that -stack-list-frames and -file-list-exec-source-files will return correct full paths to use with the path mapping.
