Re: PATCH to support native Windows builds

[Danny Smith <dannysmith at clear dot net dot nz>]

From: "Mark Mitchell"
| Danny, would you post the full patch so that DJ can more easily consier
| it?

I may be too late for this, but this  works for me,  This has
been in mingw32 binary release candidate for 3.4.0 since early May, with
no bug reports.

I didn't know where to put declarations for pex_read, pex_read_close
 but at the time I wanted to make as private as possible, so I put into new header.

It may be more politically correct to change the HOST_QUOTE_STR,
HOST_QUOTE_CHAR.HOST_QUOTED_QUOTE_STR host macros in host hook
functions, but that seemed like overkill.

Patch against  truk is attached,  I've just bootstrapped c,c++ with this and regtested
with no new
regressions.  The tests using -frepo now pass.
