[Ipopt] jipotpt.cpp compilation fails - Ipopt-3.11.9

[Kirk Abbott]

Stefan and Tony,

The suggested change works. Thanks much.

In addition, under Mingw g++, the cpp name mangling prevents the 
functions found being found.

The following change to the contrib/JavaInterface/Makefile should do the 
trick. The "-Wl,--add-stdcall-alias" would need to be added to Makefile.in

LINKFLAGS = $(CXXFLAGS)  -shared -Wl,--add-stdcall-alias

Cheers,
Kirk
