Yes, I had felt uneasy after posting as the comment confused translation
and elaboration. Yet, I had understood that something like a shell
script was to control starts of gccs for each file, basically. What is
the win over "gnatmake -jnnn" when none of the independent compilers
knows which file has already been processed? There will not normally
be a "p2.ali" after "gcc -c" has read and analyzed "p2.ads" (with'ed
by P1).

Time to look at the sources of gnatmake.
