Description: segment ordering breaks icollect

D7214 transputer version and D7205 Beta PC version icollect have a bug
which only appears when the *.cfs file uses the order attribute and the
code segment is placed lowest in memory.

/*** This is OK! ***************************************/
/*
node (element="process",stacksize = 8K, heapsize = 10K,
         order(stack = -3, code = -2),
         interface(input fs,output ts)) hello ;
*/

/*** This is no good ***********************************/
node (element="process",stacksize = 8K, heapsize = 10K,
         order(stack = -1, code = -2),
         interface(input fs,output ts)) hello ;

There are 3 possible solutions:

1) Use the PC hosted version of icollect supplied with D7214.
   This will work fine for modest sized configurations, but will
   run out of memory with large ones.

2) Use the transputer version of icollect (version 2.0.20) supplied
   with the beta release of D7205 OCCAM Toolset. If you chose this course
   make sure that you replace the D7214 version of sysproc.lib with the one
   from D7205 Beta and reconfigure. Failure to do so will cause icollect
   to complain that sysproc.lib has not been linked.

3) If one of the non-code segments can be made very small, place it
   below the code segment.

Please note that the PC hosted version of icollect distributed with
D7205 Beta also exhibits the same problem - All will be well for the product
release.
