If I am not wrong "--enable-auto-import" is already the
default on cygwin build chain ( binutils >= 2.19.51 ) so it should make
no difference on latest cygwin. Not sure for you 1.7.7 build enviroment.

About PGDLLIMPORT , my build log is full of "warning: ‘optarg’
redeclared without dllimport attribute: previous dllimport ignored "

I suspect that removing will also make no difference.
