Is there summarized table of ABI binary compatibility?

4.0.x: I don't know, but one should really not use that version

4,[1-3].x come with incompatible gfortran libraries, which have also 
different version numbers: libgfortran.so.1 to libgfortran.so.3.
Minor versions are upward compatible, i.e. programs compiled with older 
versions are compatible with newer gfortran libraries within the same 
4.y series.

Starting with libgfortran.so.3 the libraries are versioned, i.e. GCC 
4.3.0 programs will be compatible with GCC 4.4.0 libraries. (Assuming 
that you use a system which supports versioning.)
