Well, I could be wrong about this, since I'm not an expert. But I do,
  testrunner_LDADD = -ltestmain $(BOOST_LIBS)
  $(CPPUNIT_LIBS) $(GETOPT_LIBS) $(LDADD)
  testrunner_LDFLAGS = -L$(top_builddir)/testmain
don't know if that makes a big difference.

Again, I would consider doing this very different. In autoconf, figure
out if you are on windows with the AC_CANONICAL_TARGET, ..

Then, in autoconf do an AC_SUBST of the LDFLAGS you are intested in for
this platform. Then in you Makefile.am you can have

  testrunner_LDFLAGS = @TESTRUNNER_LDFLAGS@

Please take my advice with a grain of salt, not sure what your
experience level is.
