[vlc-devel] [PATCH 2/3] configure: add -Werror=incompatible-pointer-types option to the compiler

[Steve Lhomme]

This avoid using pointers of different types. It may lead to serious issues in
the code so rather than a warning, it should be avoided/fixed.

This is tested on Linux and Windows builds succesfully.
