GCC has -Werror=foo in 4.2 or later (with warning option names, not
numbers). That gives you the command-line syntax and semantics; to use it
in gfortran, you'd need either to use the common diagnostics
infrastructure or add the feature to the Fortran-specific diagnostics
code.
Not only that, but you can do -Werror -Wno-error=foo, to get errors
for everything except -Wfoo. Also, you can do
-fdiagnostics-show-options to find out which -Wfoo option generates
each warning message. It is unfortunate that this is missing from
gcc-4.2/changes.html.
