Agreed. To trace my bug down I had to do as you suggest and use 'set -x' 
and 'set +x' in various places until I narrowed down the problem. Not 
nice given the size of configure scripts.

Given the same command line then yes. If the command lines of the nested 
configures vary then maybe.

I could generate the bug every time on Win98/WinME which was an 
interesting pattern.

Sure. For the bug I listed I managed to get a small test case so this 
was not related to resource issues (that I could see).
