Definition of _gfortran_os_error?

[Alberto Luaces]

FX, Tobias

thank you both. As you said, the problem came from the g++ version, since if I 
do

$ g++-4.3 -lgfortran cbf.o cbfg.o -o cbf4

(that is, explicitly linking g++ 4.3 and gfortran 4.3 instead of g++ 4.2 
against gfortran 4.3) it works.

As Debian default g++ is 4.2 and gfortran is 4.3, I thought that they could 
safely work with each other object files. Now I see that this is not always 
the case and will match both compiler versions in the future.

Regards,

Alberto
