[Ipopt] example.for asks for MA_47

[Stefan Vigerske]

Hi,

it sounds as if HSL has reorganized the MA27 and MA47 source files 
sometime in the last 10 years, so the old Ipopt 2.3 configure doesn't 
know anymore how to build the HSL source. You would thus have to dig 
into the Ipopt 2.3 build system to update it for the current HSL 
sources, or make your own customized Makefile.

Ipopt 2.3 is no longer maintained - and that for over 10 years now.
If you want to call Ipopt from Fortran, consider using the Fortran 
interface or the current Ipopt:
