Will do the latter. (As I told earlier in this thread, I don't think
we should remove these targets without going through deprecating them
first, which should be announced in NEWS.)

Done.

I don't want to use NAME_MAX because it's too conservative on some
platforms. For example, DJGPP sets it to 12, which limits it to 8+3
names.
I know that PATH_MAX can be as large as 4K on some platforms, but I
think that waste is not important enough to care about.
I committed the patches with PATH_MAX, but if you insist, I will
change that to NAME_MAX in a separate patch.

Done.

Done.
Here's the patch that was actually committed:
2005-05-13 Eli Zaretskii <eliz@gnu.org>
* Makefile.in (go32-nat.o): Add $(top_h) to prerequisites.
* go32-nat.c: Include top.h. Update copyright years.
(init_go32_ops): Override the default value of gdbinit[] with
"gdb.ini".
* cli/cli-cmds.c (init_cli_cmds): Use gdbinit[] instead of a
compile-time literal string GDBINIT_FILENAME.
Don't define GDBINIT_FILENAME.
* top.c (PATH_MAX): Define if not defined.
(gdbinit): Declare with a constant size PATH_MAX.
* config/i386/go32.mh (XM_FILE): Remove.
* config/i386/xm-go32.h: Remove file.
