Thanks for the pointer. I think we need in general to update some of the error
message to point to the relevant option. (For the most common, namely
"-fno-range-check" we do so already; for -std=f* related ones we partially do
("Fortran 2003", "Extension:") though I think not consistently -std=legacy.)
For $ I think the following should be OK for 4.4.0.
