[lmi] wxPdfDoc: autoreconf failing with cygwin

[Greg Chicares]

Vadim--You probably don't have time to fix this properly right now,
but in the meantime can you think of any kludge that might get us
past this problem quickly so that we can start final testing of the
PDF code you've modernized?

This happens on an msw-10 machine, on which cygwin was installed
today using 'install_cygwin.bat'.

cd /opt/lmi/wxpdfdoc-scratch/wxPdfDoc-v0.9.6-28-gf66b428 \
  && export PATH="/MinGW_/bin/:/usr/local/bin:/usr/bin:[...tons of corporate 
clutter removed...]" \
  && autoreconf \
  && ./configure --prefix=/opt/lmi/local --exec-prefix=/opt/lmi/local 
--with-wx-prefix=/opt/lmi/local --with-wx-exec-prefix=/opt/lmi/local 
--build=i686-pc-cygwin --host=i686-w64-mingw32 --disable-dependency-tracking 
CFLAGS='-fno-omit-frame-pointer' CXXFLAGS='-fno-omit-frame-pointer -std=c++11'  
\
  && make install \

configure.ac:46: error: possibly undefined macro: AC_MSG_FAILURE
