Eigen is standard C++98 and so should theoretically be compatible with any compliant compiler. Whenever we use some non-standard feature, that is optional and can be disabled.</p><p style="line-height:19.1875px;font-size:13px;font-family:sans-serif;margin:0.4em 0px 0.5em">

</div>Answer is: GSL works very well on Windows too. It compiles witn MonGW<br>
without any modification, and with MSVC with minimal changes:<br>

</div>I will write that in the next days. It is the perfect moment to<br>
propose other changes to the IPOL Software Guidelines. If you have<br>
soem ideas, send me a mail and I'll add your change to the proposed<br>
