Yes, I did; sorry.

Again, my apologies; I should have provided more details, but it was
getting late by the time I posted.

I've since narrowed the problem down. It's my own program and I'm
using autotools.

The relevant part of configure.ac:
AX_BOOST_BASE([1.46])

When I do ./configure --host=i686-pc-mingw32, all goes well, and it
locates everything fine; except boost.

Looking in Makefile, I see:
BOOST_CPPFLAGS = -I/usr/include
BOOST_LDFLAGS = -L/usr/lib

Editing these to the appropriate mingw paths results in a successful
build.
