In Perl_feature_is_enabled() use cBOOL to convert the pointer to a "bool".
On some platforms which don't have a (real) bool type, bool is actually a char, and hence (sadly) it's correct for the compiler to truncate when assigning to it, instead of what the programmer thought was going to happen (testing zero or not). In Perl_feature_is_enabled(), the expression is a pointer, so if it converts to an integer with the bottom 8 bits zero, then on these platforms it would truncate to "false". Not what was expected.
