checking sys/ptem.h usability... no

configure: WARNING: sys/ptem.h: present but cannot be compiled
configure: WARNING: sys/ptem.h: check for missing prerequisite headers?
configure: WARNING: sys/ptem.h: proceeding with the preprocessor's result

configure: WARNING:     ## ------------------------------------ ##
