Re: ada compiler?

You are missing the point. You should not assume that they need command 
line option until they ask for help that require that type of answer. And if 
there is a Ada language answer then that is the answer that should be the 
given. Not a simple command line answer which is vendor and/or version 
specific.

Plus, how many beginners first downloads a GNAT version that requires:

    gnatmake -gnato -fstack-check <name>.adb  

to compile a simple program!

Most beginners that are learning Ada just use: 

Note: (Linux version)

    gnat compile <name>.adb
    gnat bind <name>.ali
    gnat link <name>.ali
    ./<name>

Extension can be optional in some cases.  Which is what I stated.
By learning the long way first a person is allowed a more deeper 
understanding and appreciation of the language. 

Only after they learn the basics should they start to use:

    gnat make <name>.adb  

without any options. 

Then in most cases, the first command option they will use is to include 
object files from other languages. Later they may get into more complex 
concepts that may require some command line options, but they should 
always use the standard Ada language concepts first. 

Now academic version of GNAT defaults to low integrity, while most 
others Ada compilers default to high integrity including GNAT PRO. And 
with a few vendors, the install program will ask for the desired 
installation integrity level.
