new GNU/Linux MARK build

As of 10 minutes ago -- latest and greatest code-based compiled (separately as a dynamic, and statically-linked executable -- one or the other is likely to work on your distro), and uploaded. You can grab mark.64.zip from links on the following page:

Should add the following:

1\ new MARK compiled using gfortran 4.9.2 (previous GNU.Linux versions compiled using 4.8.2)

2\ as a result of 'upgrading' to the new compiler, some (but not all) MARK jobs will throw an error message at you right at the end of the run -- typically looking like the following:

Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL


The new compiler generates an executable that is a bit fussier about naNs and divide by zero calcs, which can show up for some of the GOF routines. As far as we can tell, nothing to worry about.
