The rules for finding the right library to link are too primitive.
E.g. if you install BOOST for Cygwin you get only 
libboost_filesystem-gcc-mt-s-1_33_1.a
and
libboost_filesystem-gcc-mt-s.a which are identical.
I use now the following procedure to find the right library name:

if test "$ax_cv_boost_filesystem" = "yes"; then
  AC_DEFINE(HAVE_BOOST_FILESYSTEM,,[define if the Boost::FILESYSTEM library is 
available])
  for ax_lib in boost_filesystem boost_filesystem-$CC boost_filesystem-$CC-mt 
boost_filesystem-$CC-mt-s ; do
     AC_CHECK_LIB($ax_lib, main,
                 [BOOST_FILESYSTEM_LIB="-l$ax_lib" 
AC_SUBST(BOOST_FILESYSTEM_LIB) link_filesystem="yes" break], 
[link_filesystem="no"])
  done
  if test "x$link_filesystem" = "xno"; then
     AC_MSG_NOTICE(Could not link against $ax_lib !)
