Hello,
I am trying to compile the package Tk-Zinc-3.306.tar.gz by using cpansepc and rpmbuild perl-Tk-Zinc-3.306.spec

The code violates the good practice rules, but I do not want to correct the source code. Is there away to force a compilation without -Wincompatible-pointer-types option Maybe by editing the Makefile.PL ?
Thanks
