Gnu fortran does not quite get all the standards.Intel fortran does support them all, and I believe that portland group and absoft may also.

In my experience most recent versions of gfortran (at least 4.5, maybe earlier)
support about as large a set of standards as anything else (with the exception of a
few F2003 things, but then again, (almost) no one supports those comprehensively).
Definitely all of F95 + approved extensions. Non-standard extensions (DEC,
Cray Pointers pre F2003) are another matter - I don't know about those.
