[PATCH, Fortran] Support for legacy %FILL fields in STRUCTUREs

[Thomas Koenig]

Hi Fritz,

Patch looks good in principle; I really find all these DEC extensions
strange, but if they are needed for old code, why not?

Just one point:

> +	    gfc_error ("%s not allowed outside STRUCTURE at %C", "%FILL");

This should have %qs (throughout the patch).

OK for trunk with that.
