 I have followed the instructions about fixing make (otherwise compiling
 under cygwin yields)
         *** multiple target patterns.  Stop

 The problem mentioned by German Etlender above seems to still be there (I
 am also getting the warnings). Here is a section of Ipopt/config.log
 (corresponding to the latest trunk) that contains the warning:

 {{{
