I suddenly ran into another problem today (after adding some more .o 
files) - bash reported that the argument line was too long. That is, the 
expansion of "*.o" was too large. Hence, I created a shell script that 
renamed all the .o files into incremental filenames: 1.o, 2.o, etc.
Then suddenly both problems vanished...
Weird?
Maybe the first problem was related to the fact that I almost ran into 
the "*.o" expansion-boundary?

BR,
  Martin
