[PATCH RESEND v2] path: Fix a sparse warning

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

On MinGW, sparse issues an "'get_st_mode_bits' not declared. Should
it be static?" warning. The MinGW and MSVC builds do not see the
declaration of this function, within git-compat-util.h, due to its
placement within an preprocessor conditional.

In order to suppress the warning, we simply move the declaration to
the top level of the header.

Hi Junio,

Now that v1.8.3 is out, I note that this patch seems to have been
dropped (or did I miss something?).

This used to be

    [PATCH 2/6] path: Make the 'get_st_mode_bits' symbol a file static

but the change in implementation required a change in title.
This version simply moves the declaration so that the MinGW and
MSVC builds can see it.

ATB,
Ramsay Jones
