At first the change looked a bit too complicated for what it does. But i realized that, if we don't want to keep compiling things incorrectly over and over again, caching the setting is the only way to do it. And that makes the code a bit larger.

The location of this comment needs to be adjusted, since it is now out of place.

Some documentation for this function would be nice. It seems to be a helper function that returns true/false for whether a compilation succeeded or not?

It would be nice to have some documentation here explaining that we're caching true/false for whether we need to use the special workaround compilation flags.

I think this is now a helper function? Should we adjust its documentation a bit?

My understanding is that gdb_compile_ada_1 now only silently tests a compilation and doesn't actually gdb_compile_test it?
