PURPOSE OF THIS FILE

It describes the contents of the subdirectory ./PROTOTYPES, where `.'
denotes the root directory of the standard installation of SGB.


PURPOSE OF ./PROTOTYPES

The additional subdirectory ./PROTOTYPES contains a set of change files for
improved ANSI support, including all changes by Marc van Leeuwen as
provided in the ./ANSI subdirectory, by implementing function declarations
and function definitions in the form of `prototypes'.

Normally I dislike to ignore or suppress warning messages from the compiler
and/or the linker.  For the sake of simplicity, the first attempt to
install SGB on the Commodore AMIGA resulted in the ./AMIGA subdirectory,
which contains only two (2) extra files.  BUT:  The CFLAGS macro in
./AMIGA/SMakefile has the entry "IGNORE=85+93+100+132+154+161" because of
the missing prototypes in the original source files.

The independent change files in ./PROTOTYPES take care of all these
omissions, thus reducing the IGNORE variable to the single value `93';
this effects the section @<Vanilla local variables@> in ./gb_basic.w only.

The patches in ./PROTOTYPES effect all of the kernel and library modules and
some demonstration programs.  To make use of these patches a special version
of ./AMIGA/SMakefile is provided (development and test of these patches were
done on a Commodore AMIGA with the help of SAS/C++ 6.56).

HOW TO USE THESE PATCHES

Copy the contents of ./PROTOTYPES to the root directory of the standard SGB
installation.  Care has been taken to avoid any collisions with existing
files in the root directory.  Then say "make tests", "make install",
"make installdemos", and "make clean", in this order as described in
./README.  To date this holds for AMIGA users only, but support of other
operating systems and compilers is easy; the original UNIX ./Makefile
already contains provisions for the presence of change files and will
acknowledge the files from ./PROTOTYPES automatically.
