IMHO this comes from the abusive no-unused-xxx which makes some compilers not complaining.

  • it is useless (and as it adds 3 spurious characters bad) to put a variable in a catch without the intention to use it.
  • unused parameters in a function definition should be put into a comment so compilers can't see them and are happy, and readers have still an idea the parameter was for.

A special case for main(): a program without arguments should be simply define with int main() { ... } .

Reviewed commit 3a738842507872fcf9a6415772a03c6bf4d3b5df

Line 203-205: not part of your changes but immediately after a line you changed. Could you indent them appropriately before merging?

Needs the copyright date updated.

These changes are not user-visible and have no effect on the execution of the program, only on the compilation. I don't think they need a ChangeLog entry.

Merged, closing. BTW I added a recommendation in coding guidelines explaining either there is no variable, or there is one and it is used
(usually by calling what() method).
