Thanks for the review!

I've suposed it was C++ code because of the file extension. I was
looking for similar parameter operations in the code but found none
and I supposed that the concatenation could be done with +. Thanks for
the clarifications.

You mean to do:
            ppsz_argv[ppsz_argc++] = "--aspect-ratio";
            ppsz_argv[ppsz_argc++] = argv[i];

Is this correct?

I attached a corrected patch.

Best regards
