These fails are remote host related, not only specific to mingw32.  In
remote host testing, source files can be copied to the place without
directory separator.  These fails this patch fixes can be reproduced on
remote linux host with a modified board file
local-remote-host-native.exp too,

$ make check RUNTESTFLAGS="--host_board=local-remote-host-native --target_board=local-remote-host-native  py-breakpoint.exp"

FAIL: gdb.python/py-breakpoint.exp: test_bkpt_deletion: continue to breakpoint: Break at multiply.
FAIL: gdb.python/py-breakpoint.exp: test_bkpt_deletion: continue to breakpoint: Break at end.

We hack ${board}_download in local-remote-host-native.exp

proc ${board}_download { board src dest } {
    global env

    # Copy file to $HOME and return its base name.
    set destfile [file tail $src]
    file copy -force $src /home/$env(USER)/$destfile

    return $destfile
}

It is OK.
