Second windows installer for maxima 5.27.0



There is a new windows installer at 
http://billinghurst.customer.netspace.net.au/maxima-5.27.0.exe

A couple of changes from the first package

1. Describe and ? work.  My version of makeinfo was too old and the 
indexes weren't built properly
2. Updated wxmaxima to 12.04.0.  Thanks to Andrej Vodopivec for the binary
3. Updated gnuplot to 4.6.0.  Thanks to Ihor Rokach for the reminder.

As with past windows binaries this is built with an ancient mingw/msys 
and gcl/gcc-3.3.1

A couple of other problems have been reported.  I haven't been able to 
reproduce them.
