Pull request: clip : suppress unused variable warnings

This commit suppresses unused variable warnings for the variables e in the catch blocks.

The motivation for this change is to suppress the warnings that are generated on Windows when using the MSVC compiler. The warnings are not displayed when using GCC because GCC will mark all catch parameters as used.
