That's right - in nan-definitions LCGDIR and OCGDIR are set using shell
calls to guessconfig again (lines 57 & 59 in nan_definitinons.mk):
export LCGDIR = $(NAN_LIBDIR)/$(CONFIG_GUESS)
export OCGDIR = $(NAN_OBJDIR)/$(CONFIG_GUESS)

instead of possible (?)

export LCGDIR = $(NAN_LIBDIR)/$(OS)
export OCGDIR = $(NAN_OBJDIR)/$(OS)

Another solution: I added following after line 83 in tools/guess/guessconfig
(just after the cygwin patch), forcing OS to windows on mingw.

if [ "$OS" = "mingw" ]; then
   OS="windows"
   CPU=""
   OS_VERSION=""
fi

This works for me (did a clean build on obj/bin/windows and lib/windows
dirs).

I didn't see this with gcc 3.2, but have seen it since I'm using gcc 3.4
(I skipped 3.3). 3.4 also enforces stricter C/C++ syntax rules and returns
a lot more warnings.
