 Version:  3.3 (C++ Version)  |    Severity:  normal

------------------------------+---------------------------------------------
 I built Ipopt on a Linux box where the version of gfortran and gcc did not
 match:

 shark: ~> gfortran --version
 GNU Fortran (Debian 4.3-20080202-1) 4.3.0 20080202 (experimental) [trunk
 revision 132072]

 shark: ~> gcc --version
 gcc (GCC) 4.2.3 (Debian 4.2.3-1)

 You would think this could not happen when using package management under
 Linux, but in fact, the dependencies are such that it can happen even if
 you are using something like apt to do automatic updates. In this case,
 the Ipopt unit test will fail because when trying to link C++ code to
 Fortran code, configure adds "-lstdc++" to the link line, but the version
 of the stdc++ library associated with gfortran is not present in this
 case, so you end up with the error
