nmap-3.30 autoconf bug

[Chris MacKay]

I got this when I was compiling nmap-3.30

 

checking netinet/if_ether.h presence... yes
configure: WARNING: netinet/if_ether.h: present but cannot be compiled
configure: WARNING: netinet/if_ether.h: check for missing prerequisite headers?
configure: WARNING: netinet/if_ether.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to address@hidden. ##
configure: WARNING:     ## ------------------------------------ ##

nmap does compile and work properly even after this message
