	* configure.in: Try and get large file support, but it's not fatal
	if it's not there (the io-layer just ignores the high word in that
	case.)

	Check for windows builds, and only bother to look for pthreads and
	large files if we're not building for cygwin or native win32.  Not
	having pthread support on Posix systems is now a fatal error.

	* autogen.sh: Fix ACLOCAL_FLAGS - it wasn't being passed to
	aclocal

	* Initial checkin.

	This is a library emulating the win32 threading and IO API.
