CC386 is a general-purpose 32-bit C compiler. It is not an optimizing compiler but given that the co

IMAKE basically parses the declarations in the make file and makes an
internal database describing them.  Some macros are expanded as soon
as they are encountered (such as recursive definitions) while others
are expanded when they are used - so the last definition counts.

After making the internal database imake starts processing the targets 
specified on the command line, or if there are none it processes the first
explicit target in the file.  For each target it processes it first
recursively processes all dependent targets, then if it finds that any
of those targets changed it executes the commands associated with the 
target.  At the lowest level the determination as to whether a target
changed is based on a comparison of time stamps between the target and
its source files.

The following source files make up this project:

ALLOCATE.C  - allocate memory
ARGS.C      - argument parsing
DUMP.C      - functionality for dumping the database to the console
ENV.C       - read environment into database
EXT.C       - simple file extension utilities
FATAL.C     - print a fatal error and exit
IF.C        - handle conditional processing
IMAKE.C     - main routine, command line parsing
INPUT.C     - basic routines for file level handling of the make files
MACROS.C    - macro handling
MAKER.C     - determination of what commands need to be executed to
            - bring the target(s) up to date
MODULE.C    - IEEE695 object file parser (not used by 386 tool chain)
PARSER.C    - make file parsing routines
PHASH.C     - hash table functions
PHITEXT.C   - phi text functions
PSTR.C      - wide character functions
REGISTER.C  - register a rule in the database
SPAWNER.C   - execute those commands that need to be executed to 
            - bring the targets up to date
SRCHPATH.C  - search for a file along a path spec
SYMCHAR.C   - phitext - ctype style arrays
USAGE.C     - usage and banner routines
ALLOCATE.H  - declarations for memory allocation

There are also a number of '.p' files that get included by the various
h files to declare prototypes
