  Amiga environment:-
  
       AMIGA 1200 with HDD and 4MB Fastram.
       AMIGA OS_3.0.x.

       FS-UAE on OSX 10.14.1 and Linux Mint 19.
       Standard default AMIGA OS_3.0.x install or better.
       (AMIGA OS 3.1.x is preferred however.)
       Full ADE install is needed.

  Inserting Inaccessible Private Strings Inside C Code Compiled Using GCC.
  ------------------------------------------------------------------------

  This assumes that you have 'ADE' fully installed and configured.

  Recently on this site this thread started, which I solved:
  https://www.unix.com/programming/279864-embed-text-c-code.html
  And I finalised it here:
 
https://www.unix.com/programming/281218-private-string-embedded-inside-c-code.ht
ml

  Well I thought this DEMO might be of use to we AMIGA nutters so the code
  embed_private_strings.c.txt was created.

  Just download embed_private_strings.c.txt and rename to
  embed_private_strings.c inside your /full/path/to/ADE/home/ drawer.

  Start ADE as per the _manual_ or instructions and go to the drawer where
  this code is saved.

  This will give the facility to have any short, 120 character, (byte),
  string in any function in C code for the UNIX like environment. It is
  possible to have literally thousands of characters, but the limitation is
  that each string must have one newline, and any extra NULL bytes to pad
  the length to an even number.
  Without any mods' this compiles on gcc 2.95.3 in ADE on AMIGA OS_3.0.x,
  on gcc 4.2.1 on OSX 10.14.1, and on gcc 7.3.0 on Linux Mint 19.
  It is surprising the difference between gcc versions 2.95.3 and 4.2.1 in
  the compiled code layout.

  When the DEMO is run the result looks like this, using OSX 10.14.1, (but
  AMIGA OS looks the same):

(Note the filename is 'a.out' and is executable by default.)
And a portion of the HEXDUMP for the AMIGA executable looks like this:

    Testing Evaluation:-
    --------------------

    All WinUAE, FS-UAE and Classic AMIGA test conditions were/are running
    standard OS 3.0.x and using standard ~topaz 8~ fonts throughout. The
    minimum hardware requirements ARE needed however.

    I have no idea what strange configuration setups will create so refer
