 Hi,

 if I compile Ipopt/trunk without any linear solver available, then the
 linear_solver option does not work correct. Here is what
 print_options_documentation gives me:
 {{{
 linear_solver                 ("ma27")
    Linear solver used for step computations.
    Possible values:
     - use the Harwell routine MA27 [ma57]
     - use the Harwell routine MA57 [pardiso]
     - use the Pardiso package [wsmp]
     - use WSMP package        [taucs]
     - use TAUCS package (not yet working) [mumps]
     - use MUMPS package       [custom]
     - use custom linear solver [Determines which linear algebra package is
 to
                                be used for the solution of the augmented
                                linear system (for obtaining the search
                                directions). Note, the code must have been
                                compiled with the linear solver you want to
                                choose. Depending on your Ipopt
 installation,
                                not all options are available.]
 }}}

 Please, please, please, have a look at !IpAlgBuilder.cpp:120 and, e.g.,
 add some {{{#else}}} branch for the {{{#ifdef COIN_HAS_MUMPS}}}.

 Thanks,
 Stefan
