/* 1. MACHINE_STRING should be set to the name of the machine or OS. */

/* USE_TEMPORARY_FILES - use scratch files for workspace, not memory, */

/* PROMPT_INPUT - prompt input (don't use Unix-style command line) */
/* TIME_UNAVAILABLE - don't use ANSI time routines to work out today's */
/* date */
/* CHAR_IS_UNSIGNED - if on your compiler the type "char" is unsigned */
/* by default, you should define this */
/* HAS_REALPATH - the POSIX realpath() function is available to */
/* find the absolute path to a file */
/* */
/* 3. An estimate of the typical amount of memory likely to be free */
/* should be given in DEFAULT_MEMORY_SIZE. */
/* For most modern machines, HUGE_SIZE is the appropriate setting, but */
/* some older micros may benefit from SMALL_SIZE. */
/* ------------------------------------------------------------------------- */
#define LARGE_SIZE 1
#define SMALL_SIZE 2
#define HUGE_SIZE 3
/* ------------------------------------------------------------------------- */
/* 4. Filenaming definitions: */
/* */
/* It's assumed that the host OS has the concept of subdirectories and */
/* has "pathnames", that is, filenames giving a chain of subdirectories */
/* divided by the FN_SEP (filename separator) character: e.g. for Unix */
/* FN_SEP is defined below as '/' and a typical name is */
/* "users/graham/jigsaw.z5". */
/* White space is not allowed in filenames, and nor is the special */
/* character FN_ALT, which unless defined here will be a comma and will */
/* be used to separate alternative locations in a path variable. */
/* */
/* If NO_FILE_EXTENSIONS is undefined then the OS allows "file extensions" */
/* of 1 to 3 alphanumeric characters like ".txt" (for text files), ".z5" */
/* (for game files), etc., to indicate the file's type (and, crucially, */
/* regards the same filename but with different extensions -- e.g., */
/* "frog.amp" and "frog.lil" -- as being different names). */
/* (The file extensions defined below are widely accepted, so please use */
/* them unless there's a good reason why not.) */
/* */
/* You should then define STANDARD_DIRECTORIES (you can define it anyway) */
/* in which case Inform will expect by default that files are sorted out */
/* by being put into suitable directories (e.g., a "games" directory for */
/* story files). */
/* */
/* If it's convenient for your port you can alter the detailed definitions */
/* which these broad settings make. Be careful if NO_FILE_EXTENSIONS */
/* is set without STANDARD_DIRECTORIES, as then Inform may */
/* overwrite its source with object code. */
/* */
/* 5. Filenames (or code related to filenames) for the three temporary */
/* files. These only exist during compilation (and only if -F1 is set). */
/* Temporary_Name is the body of a filename to use */
/* (if you don't set this, it becomes "Inftemp") and Temporary_Directory */
/* is the directory path for the files to go in (which can be altered on */
/* the command line). On some multi-tasking OSs these filenames ought to */
/* include a number uniquely identifying the process: to indicate this, */
/* define INCLUDE_TASK_ID and provide some code... */

/* #define INCLUDE_TASK_ID */
/* #ifdef INFORM_FILE */
/* static int32 unique_task_id(void) */
/* { ...some code returning your task ID... */
/* } */
/* #endif */
/* */
/* 6. Any other definitions specific to the OS or machine. */
/* (In particular DEFAULT_ERROR_FORMAT is 0 on most machines and 1 on PCs; */
/* it controls the style of error messages, which is important for some */
/* error-throwback debugging tools.) */
