/* If ! defined(OM_NDEBUG) and (defined(OM_TRACK) or defined(OM_CHECK)
   then omDebug routines are used for memory allocation/free:

   The omDebug routines are controlled by the values of OM_TRACK, OM_CHECK
   and OM_KEEP.  There meaning is roughly as follows:
   OM_TRACK: strored with address                              : extra space
     0     : no additional info is stored                      : 0
     1     : file:line of location where address was allocated : 1 word
     2     : plus backtrace of stack where adress was allocated: 6 words
     3     : plus size/bin info and front-, and back padding   : 9 words
     4     : plus file:line of location where adress was freed : 10 words
     5     : plus backtrace of stack where adress was allocated: 15 words
   OM_CHECK: checks done
     0     : no checks
     1     : constant-time checks: i.e. addr checks only
     2     : plus linear-time checks and constant related bin check
     3     : plus quadratic-time checks and linear-time related bin checks and
             constant time all memory checks
     4     : and so on
     ==> for OM_CHECK >= 3 it gets rather slow
   OM_KEEP:  determines whether addresses are really freed  (
     0     : addresses are really freed
     1     : addresses are only marked as free and not really freed.

   OM_CHECK, OM_TRACK, and OM_KEEP can be set on a per-file basis 
   (as can OM_NDEBUG),  e.g.:
     #define OM_CHECK 3
     #define OM_TRACK 5
     #define OM_KEEP  1
     #include "mod2.h"
     #include <omalloc/omalloc.h>
   ensures that all memory allocs/free in this file are done with 
   OM_CHECK==3 and OM_TRACK==5, and that all addresses allocated/freed 
   in this file are only marked as free and never really freed.
 
   To set OM_CHECK, OM_TRACK and OM_KEEP under dynamic scope, set 
   om_Opts.MinCheck, om_Opts.MinTrack to the respectiv values and 
   om_Opts.Keep to the number of addresses which are kept before they are 
   actually freed. E.g.:
     int check=om_Opts.MinCheck, track=om_Opts.MinTrack, keep= m_OPts.Keep;
     om_Opts.MinCheck = 3; om_Opts.MinTrack = 5; omOpts.Keep = LONG_MAX;
     ExternalRoutine();
     om_Opts.MinCheck = check; omOpts.MinTrack = track; omOpts.Keep = keep;
   ensures that all calls omDebug routines  occuring during the computation of
   ExternalRoutine() are done with OM_CHECK==3 and OM_TRACK==5, and 
   calls to omFree only mark addresses as free and not really free them.

   Furthermore, the value of OM_SING_KEEP (resp. om_Opts.Keep) specifies 
   how many addresses are kept before they are actually freed, independently 
   of the value of OM_KEEP.

   Some tips on possible values of OM_TRACK, OM_CHECK, OM_KEEP:
   + To find out about an address that has been freed twice, first locate the
     file(s) where the error occured, and then at the beginning of these files:
       #define OM_CHECK 3
       #define OM_TRACK 5
       #define OM_KEEP  1
       #include "mod2.h"
       #include <omalloc/omalloc.h>
     Under dynamic scope, do (e.g., from within the debugger):
       om_Opts.MinCheck = 3; om_Opts.MinTrack = 5; omOpts.Keep = LONG_MAX;
   + to find out where "memory corruption" occured, increase value of 
     OM_CHECK - the higher this value is, the more consistency checks are 
     done (However a value > 3 checks the entire memory each time an omalloc 
     routine is used!)
   
   Some more tips on the usage of omalloc:
   + omAlloc*, omRealloc*, omFree*, omCheck* omDebug* omTest* rotuines 
     assume that sizes are > 0 and pointers are != NULL
   + omalloc*, omrealloc*, omfree* omcheck*, omdebug* omtest* routines allow
     NULL pointers and sizes == 0
   + You can safely use any free/realloc routine in combination with any alloc 
     routine (including the debug versions): E.g., an address allocated with
     omAllocBin can be freed with omfree, or an adress allocated with 
     om(Debug)Alloc can be freed with omfree, or omFree, or omFreeSize, etc.
     However, keep in mind that the efficiency decreases from 
     Bin over Size to General routines (i.e., omFreeBin is more efficient than
     omFreeSize which is more efficient than omFree, likewise with the alloc
     routines).
   + if OM_CHECK is undefined or 0, then all omCheck routines do nothing
   + if OM_CHECK and OM_TRACK are both undefined (or 0), or if OM_NDEBUG is 
     defined, then the "real" alloc/realloc/free macros are used, and all 
     omTest, omDebug and omCheck routines are undefined
   + to break after an omError occured within a debugger, 
     set a breakpoint on dErrorBreak
   + to do checks from within the debugger, or to do checks with explicit 
     check level, use omTest routines.
