Subject: [ruby-core:24828] request: add optional ability to *not* override windows IO methods

Background:
currently when you require<ruby.h> in a c extension, on windows this calls

#define select rb_w32_select
#define fstat rb_fstat_w64 # something like that, on 1.9
etc.
etc.

Sometimes one wants to interface with ruby but still use direct IO
calls.  This currently requires

#include<ruby.h>
#undef select
#undef fstat
....

which is unweildy and time consuming and error prone, and causes some
surprising compiler clashes.

One option to overcome:
allow users to specify
#DONT_OVERRIDE_WINDOWS
or such before the include ruby.h

and if that directive is set, don't override anything.
Would that work?
Thanks.
