I am trying to port a program that is compiled succesfully on Dec Ultrix,
but i can't compile it on Solaris.  The problem seems to be with the 
following directive:

#define CONCAT(f) f##_ptr

it is supposed to append a string '_ptr' at the end of the variable f.

suppose you do CONCAT(head) then the result should be head_ptr

Apparently Solaris and a few other systems don't like this kind of directive.

If you know other directive that does the same thing, please let me know.
Any help is appreciated.

Thank you,
  Suwanto
