Makefile.am as reported by David Fang <fang@csl.cornell.edu>
* Fixed the section in ngspice.texi where the use of @/ in a @url{} was
giving problems. Actually this whole section on the Windows port is now
out-of-date, and date link was broken, so I have replaced it with something
more appropriate. Thank you to Stuart Brorson for reporting these problems.
