I meant exactly what I wrote: An Ada 95 program does not need a main
procedure (or main function, for that matter).  That is, an Ada 95
program can consist of a bunch of library packages, without any main
subprogram.  This is different from Ada 83, which required a main
subprogram (called a main program in Ada 83, despite the fact that it's
not a program).

Note "optionally" and "if specified" in 10.2(7) -- the user is not
required to have a main subprogram.  Note "if the partition has one" in
10.2(21) and "if there is no main subprogram" in 10.2(23).  See also
10.2(34), which explains the reason.  See also AARM-10.2(34.e), which
says that this change is a language extension.
