I think someone already tried to respond, before this post came to my e-mail server. This mailing list is about cygwin and the gcc which is installed with it, not about some other compiler which you might have installed. Windows environment variables have no bearing on cygwin gcc. If you install cygwin gcc normally, its own include directory should be mounted at /usr/include. Following the advice in the URLs at the bottom of your post would enable people to see whether you installed cygwin properly. I don't know whether installing some include directory in a similar looking Windows directory would interfere, but it's best to install compilers in the intended ways, particularly when that assures they don't interfere with each other. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
