gcc version 2.2.2, on Interactive version 3.0

It seems that when compiling without the optimiser and with debug on
in-line functions do not get in-lined, resulting in undefined symbols
on the final link.

(jay)$ g++ -c -O -I../include -Di386ix prctxt.C
(jay)$ nm prctxt.o | fgrep _12symbol_stacki
the final link worked fine

(jay)$ g++ -c -g -I../include -Di386ix prctxt.C
(jay)$ nm prctxt.o | fgrep _12symbol_stacki
__12symbol_stacki   |       0|extern|                  |      |     |

__12symbol_stacki was undefined on the final link.

This was an in-line function, here is an extract from the header file.

#pragma interface
class symbol_stack
{
.....
public:
  symbol_stack(int sz = 20 ) 
  {
    top = s = new symbol*[size = sz];
  }
.....
};



Since you can run with -O and -g its not really a problem once you
know what is going on!
