I assume that statement is in a gpr file.

By "doesn't parse" do you mean "throws an error" or "doesn't seem to
use the value"?

Ah; you want to set the main program in the Emacs Ada mode project
settings from the statment in the GPR file.

This is problematic; there can be many programs listed in the "for
Main" statement (the parens mean it's a list of strings); which would
we use for the single current Emacs Ada mode project main program?

Also, the current output from gnatls doesn't list this setting. I
don't see any 'gnat ...' commands that do output this information. So
we'd have to add one, after figuring out the Ada code that would
return it (the 'gnat list' source is _not_ pretty!).

As a work-around, you can set a single main program in the Emacs Ada
mode project file.
