Currently it does nothing special and just hopes the compiler figures
it out.  I've had a TODO list entry for a long time to add a source-file
property to mark files as free- or fixed-format.

Actually you can just set the COMPILE_FLAGS target or source file
property to include -qfixed or -qfree on this compiler.  This is a
work-around until the above-mentioned property is added.
