The way "recompile file" can be harmful is precisely in that it may not
find the project (.adp or .gpr, whatever) file, or use the wrong one.
For example it might compile to the wrong object directory, or with the
wrong options.  Or, it might fail to compile altogether because gnatmake
doesn't find units the current file depends on, etc.

What I meant to say is that, *if* you have a multi-file project, then
you *want* to use the project's settings to compile and nothing else.

There is currently no way to tell ada-mode that "the current file is not
part of the current project"; but there is a way to override the default
compilation command, which uses the project settings.
