great to know you are trying this, it has been a long time i haven't.

i have been compiling and using aubio successfully on windows with
libsamplerate and libsndfile. what new versions of these two are you
referring to?

I am surprised a bit you don't have pkgconfig, it is in cygwin since
2002 apparently: http://cygwin.com/packages/pkgconfig/

I would hope mkinstalldirs has also been fixed in a recent version.
A few more questions:

You added some tests about prefix and exec_prefix. Does
AC_DEFAULT_PREFIX fail on your system?

The check for fftw3.h header is commented. Does it also fail?

Also, why are @FFTWLIB_FLAGS@ needed in examples/Makefile.am? It
contains only -I/usr/include here, which is already included by default.
Maybe you need to set CPPFLAGS?

You also replaced darwin* with *darwin*, and ming* with *ming*. how is
'host_os' reported on your system?

Cheers, piem
