This 'workaround' might only work with gcc/f77. But not all 
compiler-drivers are that intelligent.

This is not a complete solution IMHO. What if you want to link an 
executable that contains object-files that are compiled by the fortran 
compiler as well as the C++ compiler? On that case you need to link with 
the Fortran library as well as the C++ library!

How this should be handled IMHO is that the runtime libraries of the 
compiler used generate an object-file should be propagates just like 
usage-requirements on the object-file. These usage-requirements are thus 
propagated to the executable when it will be linked using this object-file.
