I wasn't sure what directory I should cd into before 'git clone',
so I did this:

cd ~/src/3rdparty
git clone https://github.com/vadz/xmlwrapp.git
cd xmlwrapp
./bootstrap
mkdir ~/build/xmlwrapp-msw
cd $_

I guess you must have done that in ~/src because the first line of
the 'configure' command didn't work for me, so I changed it thus:

/home/greg/build/xmlwrapp-msw[1]$~/src/3rdparty/xmlwrapp/configure \
      --disable-shared --disable-tests --disable-docs \
      --with-boost=$HOME/msw/i686-w64-mingw32 \
      --prefix=$HOME/msw/i686-w64-mingw32 \
      --host=i686-w64-mingw32 \
      PKG_CONFIG_LIBDIR=$HOME/msw/i686-w64-mingw32/lib/pkgconfig

The other paths in this command are absolute and don't need any
adjustment. But when I run it, I get:
  [many unremarkable lines snipped]
checking for Boost headers version >= 0.0.0... no
configure: error: cannot find Boost headers version >= 0.0.0

This option seems crucial:
  --with-boost=$HOME/msw/i686-w64-mingw32
The command I used to "install" boost was
  cp -a boost ~/msw/i686-w64-mingw32/include
copied and pasted from your instructions, and boost seems to be there:

/home/greg/build/xmlwrapp-msw[1]$ls $HOME/msw/i686-w64-mingw32
bin      lib                    libboost_regex.a   man
include  libboost_filesystem.a  libboost_system.a  share
/home/greg/build/xmlwrapp-msw[0]$ls $HOME/msw/i686-w64-mingw32/include |head
accumulators
algorithm
aligned_storage.hpp
any.hpp
...

I tried adding '/include' to the boost path:

/home/greg/build/xmlwrapp-msw[0]$~/src/3rdparty/xmlwrapp/configure \
      --disable-shared --disable-tests --disable-docs \
      --with-boost=$HOME/msw/i686-w64-mingw32/include \
      --prefix=$HOME/msw/i686-w64-mingw32 \
      --host=i686-w64-mingw32 \
      PKG_CONFIG_LIBDIR=$HOME/msw/i686-w64-mingw32/lib/pkgconfig 2>&1 |less

but the result is the same:

checking for Boost headers version >= 0.0.0... no
configure: error: cannot find Boost headers version >= 0.0.0

I checked 'config.log'...

/home/greg/build/xmlwrapp-msw[0]$tail -n5 config.log
#define HAVE_STDINT_H 1
#define HAVE_UNISTD_H 1
#define LT_OBJDIR ".libs/"

configure: exit 1

...but that doesn't seem to help. Looking in 'configure', I see:
   1477   --with-boost=DIR        prefix of Boost [guess]
and then around line 15670 I get a vague impression that maybe
the script expects
  path/to/include/boost/some_boost_file.hpp
where I have
  path/to/include/some_boost_file.hpp
Is that worth trying after my lunch break?
