Is the pure-Ruby version acceptable for you?

I wonder if extconf.rb should just bail out with

	if RUBY_PLATFORM =~ /win32/i
	  raise "C ext not supported on RUBY_PLATFORM=#{RUBY_PLATFORM}"
	end

if this can't be fixed...

I guess ruby/win32.h defines clock_gettime...

Can you share the generated Makefile and maybe mkmf.log, too?

I can't do much to fix this problem since I don't use non-Free
systems, but a non-intrusive patch would be acceptable
(even if it's just bailing on the C extension build to force
use of the pure Ruby version).

Can you comment out sys/time.h?

I might fix that aliasing independently in a few minutes...


On a side note: I hope to drop the C extension if the pure
Ruby version can offer acceptable performance nowadays.  I'd be
much happier if there's zero chance of somebody downloading an
unauditable pre-compiled binary.
