This document contains information on compile time defines for Mathomatic.

To compile Mathomatic for MS-DOS, define "IBM_PC".
To compile for UNIX, define "UNIX".
If you are compiling for Linux, define "UNIX" and "LINUX".
Defining "LINUX" will not work for Debian Linux, so just define "UNIX".
To compile Mathomatic for a generic system, simply compile with no defines.

Define "MSC" if you are using the Microsoft C compiler.

Define "READLINE" and include the readline libraries at link time to
use readline mode.  This will allow command line editing and history
in UNIX/Linux.

Define "SILENT" to suppress helpful messages while manipulating equations.
This is useful when using Mathomatic as a symbolic math library.  It can
also be used to make Mathomatic like all the other math programs out there
(which rarely display helpful messages).  This also reduces the size of
the code, somewhat.

Define "NO_COMPLEX_ROOTS" to leave out "complex.c".
"complex.c" is the only module that requires trigonometric functions
from the C math library.

Define "SECURE" to disable file reading and writing and shell escape.
This is useful when making Mathomatic available to the public through
telnet or CGI programs.  It is also useful when making ROMable code.
