Sorry, I realised that this was not the best list afterward.

An other question about long double printing, shouldn't the printer  
append a 'L' suffix to long double literal ? As the printer does not  
output an exact value (due to the convertion to double), it will at  
least helps to defined that the value was correctly interpreted as a  
long double.
