With 2 exceptions: the AC_REQUIRE lines were causing a problem - so I've dnl'd them barring some feedback from a more m4 knowedgable person. I'm a little unsure whether overriding both CPPFLAGS and CFLAGS is a good idea, but the reason is that non automake makefile.in's may not use CPPFLAGS, so CFLAGS does need to be set. Not setting CPPFLAGS results in AC_CHECK_HEADER tests for win32 headers failing. The upshot is that in automake environments -mwin32 is added twice... If there's an easy way to test for the presence of automake in the macro, I could make this conditional... I'll visit the automake doco in more detail later today...
