fix cygwin port cont'd

after investigation on pull request #20, using import library does make progress a bit for `--enable-native` on cygwin. following commits also include:

* removing useless `$host_os` conditional `SO_EXT`,
* cleaning up `test` style in `configure.ac`,
* **3 FIXMEs**. :stuck_out_tongue_closed_eyes: 

the next step is to resolve link errors WRT `ieee.numeric_std`, IMHO.

any thoughts?

```
$ ./autogen.sh && ./configure --enable-native && make -k V=1
