Comment:

 Hi,

 The IpStdCInterface.h header file is meant for the C compiler interface,
 and "const" - as far as I know - is not part of ANSI C.  Therefore I would
 be hesitant to include the const keyword in a C header file.  If you are
 using a C++ compiler to handle this code, "const" will work.

 The AC_C_CONST macro could be helpful, but then we would have to include
 the config_ipopt.h file as well, and so far we were nicely able to avoid
 this for the C interface.

 Unless there are really strong reasons to make the C interface have C++
 attribute, I suggest we leave it as it is for now.

 But we can leave the ticket open as possible enhancement later.


 Thanks

 Andreas
