In order to complete the fix for 1.5 Cygwin API,
we need to fix the compilation failure in
remote-fileio.c source.
Christopher said in a previous email that he
didn't have an opinion about that part.

I do not really know if there is a specific maintainer for this
file... Could someone (a global maintainr?)
please review this patch?

* remote-fileio.c:
(__USE_OLD_CYGWIN_API_): New macro, set for
older cygwin API that does not have cygwin_conv_path.
(cygwin_conv_path): New static function emulating
new cygwin API.
