+Patch by Robert Scheck <robert at fedoraproject.org> for zarafa >= 7.0.8, which solves
+the invalid conversion that causes since zlib >= 1.2.8 a build failure like this:

+ECLogger.cpp:169:14: error: invalid conversion from 'gzFile_s* (*)(const char*,
+  const char*)' to 'ECLogger_File::open_func {aka void* (*)(const char*, const
+  char*)}' [-fpermissive]

+ECLogger.cpp:171:16: error: invalid conversion from 'int (*)(gzFile, const char*,
+  ...) {aka int (*)(gzFile_s*, const char*, ...)}' to 'ECLogger_File::printf_func
