 PRECC 2.42 COMPILER COMPILER    Copyright Peter T. Breuer, August  1994

------------------------------------------------------------------------

RUNNING INSTRUCTIONS.

a) run precc over your script file to produce a C file

        preccx  foobar.y  foobar.c

b) compile the c file, using the appropriate precc library as final
   resource. For example, under unix, using the libcc.a library in the
   current directory:

   gcc -o foobar foobar.c -L . -lcc  -D__STDC__
 
   The flag __STDC__ could be defined, but most ansi compilers do this for
   you when required. You DON'T need to set __STDC__ if compiling under
   TURBO-C, for instance, because either the compiler will be in ansi mode
   and set it for you, or it will be in TC mode, which is a superset, and
   the flag will not be set and it doesn't matter. All you have to check
   for is that the compiler not be in K&R mode, because that is a subset of
   ansi and PRECC uses ansi prototypes that are not K&R compatible.
   
   The compilation instructions under TURBO-C are

   tc foobar.c /b
   
   and you should have prepared a project file in the same directory

                foobar.prj

   which lists foobar.c as its main file, has the directory where you put the
   cc.h and ccx.h files in its list of `include' directories, and refers
   specifically to one of the library files preccx??.lib in the file list.
   MAKE SURE THAT THE LIBRARY MATCHES THE MEMORY MODEL AND TOKEN SIZE!!
   For example, use preccx1c.lib for `char' TOKENs and the `compact' model.

c) run the executable that results, typing into it to test it out:

        foobar
