Are there really Ada compilers that have "required file names"?
Certainly GNAT does not have required file names. In fact,
unlike the case in C, there is in GNAT a default file naming
convention that means that, when you reference a spec, you can
do it just using the unit name (unlike the case in C, where you
have to mention the actual file name of a header file, which is
unpleasant, since it means that when file names change from one
system to another, you have to modify the sources).
If you don't think this is
a problem, you should have to deal with the 8+3 limitations
in early DOS C compilers, a *real* pain!!!! If you are using
your own file names, that do not correspond to the GNAT
defaults, then you have to specify the file names, but this
is done in a separate file, not in the source files themselves.
So this to me is one place that Ada clearly wins over C, rather
than loses.

Well an order of magnitude would be a catastrophe, but in fact
the statement is just false. If your Ada compiler produces
junk code, get another one. In the case of GNAT, the compiler
uses exactly the same code generator as the GNU C compiler or
the G++ compiler, so for comparable source code, you get
identical object code.
