Checking out the latest version of libtickit from https://github.com/leonerd/libtickit, successful compilation is achieved by setting
CFLAGS thus:
make CFLAGS='-D_POSIX_C_SOURCE=199309L -D_BSD_SOURCE'
_POSIX_C_SOURCE=199309L as defining this is guarded by __GLIBC__ definition. ???
_BSD_SOURCE is required as glibc is 2.17 and advice regarding its use is:

_DEFAULT_SOURCE alone is currently used https://github.com/leonerd/libtickit/blob/3c2aa68aa3e0964f392c51d82da6da237ed8ff36/include/tickit.h#L8-L11
