* defs.h: Adjust comment.

	* filesystem.h, filesystem.c: New files.
	* Makefile.in (SFILES): Add filesystem.c.
	(COMMON_OBS): Add filesystem.o.
	* solib.c (solib_find): Handle DOS-based filesystems.  Handle
	different target and host path flavours.
	* arm-symbian-tdep.c (arm_symbian_init_abi): Set
	has_dos_based_file_system on the gdbarch.
	* arm-wince-tdep.c (arm_wince_init_abi): Ditto.
	* i386-cygwin-tdep.c (i386_cygwin_init_abi): Ditto.
	* i386-tdep.c (i386_go32_init_abi): Ditto.
	* gdbarch.sh (has_dos_based_file_system): New.
	* gdbarch.h, gdbarch.c: Regenerate.
	* NEWS: Mention improved support for remote targets with DOS-based
	filesystems.  Mention new `set/show target-file-system-kind'
	commands.

	gdb/doc/
	* gdb.texinfo (Commands to specify files): Describe what how GDB
	looks up DOS-based filesystem paths on the system root.  Document
	the new `set/show target-file-system-kind' commands.
