Internal compiler error

[Michael Ward <mward at are dot Berkeley dot EDU>]

egcs requested a bug report.  The code it puked on is probably illegal in
C++ -- I'm just learning.

matrix.cc: In method double & matrix::operator ()(unsigned int, unsigned int)':

the offending code fragment:

 reference cv (uint i, uint j) {return (*this)[i];}
 reference mx (uint i, uint j) {return *next();}
 reference operator() (uint i, uint j) {return this->ref(i,j);} // *** Line 38 ***
};
