[FYI 0/3] trivial unused fixes

[Tom Tromey]

I'm checking these in.

Two of these patches just remove declarations that no longer have
corresponding definitions.

The third removes the "use_windows" global and the corresponding field
from struct capture_main_args.  I had long assumed that this was used
by Insight, but recently I checked the sources and I found that
nothing checks this variable.

Tested by rebuilding and grep.

[FYI 2/3] remove use_windows

[Tom Tromey]

Nothing actually uses use_windows, not even Insight.  So, this patch
removes it.

2014-01-13  Tom Tromey  <tromey@redhat.com>

	* defs.h (use_windows): Remove.
	* gdb.c (main): Update.
	* main.c (captured_main, gdb_main): Update.
	* main.h (struct captured_main_args) <use_windows>: Remove.
	* top.c (use_windows): Remove.
