NAME
machine.h - include file for system environment
SYNOPSIS
#include <machine.h>
DESCRIPTION
This include file defines the current machine environment. It is used by one routine, align(C-3), to determine the proper data field alignment for the hardware.
The file shown below is the master version of machine.h. Note that this file is made up of different categories (Operating System, Hardware, Manufacturers, etc). One item in each category should be set to "1" to define the machine being used. Examine \cbase\include\cbase\machine.h for the appropriate settings for your system.

* The following defines macros to test for path separator characters
* and to generate them. They are designed to work with "bizarre"
* systems that have more that one valid path separator character
* (like MS-DOS). They are described below:
*
* PATHCHAR the "preferred" path separator character. Use this
* whenever you are generating a file name with a path
* separator character in it
*
* PATHSTR like PATHCHAR but a string constant rather than a
* character constant
*
* PATHSET a string containing all the valid path separator
* characters. The first character is the same as
* PATHCHAR
*
* ISPATH(c) returns true (!= 0) if the character is path separator,
* false (0) otherwise
*
* LASTPATH(s) returns a pointer to the last path separator character
* in s, or NULL if there are no path separator characters
* in s
*
* FIRSTPATH(s) returns a pointer to the first path separator character
* in s, or NULL if there are no path separator characters
* in s
*
* ISABSPATH(s) returns true (!= 0) if the string s represents an
* absolute path, or false (0) otherwise
