			   INSTALLATION NOTES
			      <11-Nov-1989>

   At compile-time (or here, if compile-time definition is not
   available), set non-zero ONE OS_xxxx operating system flag, and if
   more than one compiler is available, ONE compiler flag:

    Operating Systems        Compiler(s)
    =================        ===========
    OS_ATARI
    OS_BS2000                CCD_2000
    OS_BSD
    OS_MVSXA                 IBM_C370
    OS_VMCMS                 IBM_C370
    OS_PCDOS                 IBM_PC_MICROSOFT
    OS_SYSV
    OS_TOPS20                KCC_20 or PCC_20
    OS_VAXVMS
    OS_XENIX
    =================        ===========

   If no OS_xxxx symbol is defined, OS_BSD is assumed.

   Standard C prototypes are now required.

   All function declarations in MakeIndex are contained at the end of
   this file.

   If the host system restricts external names to 6 characters, set
   SHORTNAMES non-zero in the appropriate OS_xxxx section below.

   Installing MakeIndex under BS2000 requires at least Version 8.5
   supporting Multiple Public Volume Sets (MPVS). Define WORK in this
   file to your CATID (default :w:) for temporary files (.ilg, .ind),
   in case of no MPVS support define WORK to NIL.

*/

/**********************************************************************/

/*
 * Establish needed operating symbols (defaulting to OS_BSD if none
 * specified at compile time).  If you add one, add it to the check
 * list at the end of this section, too.

/*====================================================================
Many arrays in MakeIndex are dimensioned [xxx_MAX], where the xxx_MAX
values are defined below.  The use of each of these is described in
comments.  However, no run-time check is made to ensure that these are
consistent, or reasonable!  Therefore, change them only with great
care.

The array sizes should be made generously large: there are a great
many uses of strings in MakeIndex with the strxxx() and sprintf()
functions where no checking is done for adequate target storage sizes.
Although some input checking is done to avoid this possibility, it is
highly likely that there are still several places where storage
violations are possible, with core dumps, or worse, incorrect output,
ensuing.
