>Description:
t_dup fails to compile on FreeBSD with clang for the following reasons:
- It doesn't #include stdbool.h, but references false/true (stdbool.h is 
required per POSIX to access these definitions).
- It has a duplicate static declaration for the check_mode function, which 
isn't required.
