Can't compile file with '=' in path

[D-a-n-i-l-o]

If there is a '=' char in the path, Mx2cc can't compile.

Examples:
./mx2cc_macos makeapp -run /users/name/monkey2/=TESTS=/file.monkey2
./mx2cc_macos makeapp -run "/users/name/monkey2/=TESTS=/file.monkey2"

Error message:

Mx2cc version 1.1.15

***** Fatal mx2cc error *****

Invalid option: '/users/name/monkey2/'

After removing the '=' from the directory name everything is fine, for example "-TESTS-".
