linux/time.h: present but cannot be compiled

[Faithful]

As I was configuring xinetd 2.3.11 on a slightly varied linux from scratch 
machine (kernel 2.4.20) the script output this and continued configuring:

checking for linux/time.h usability... no
checking for linux/time.h presence... yes
configure: WARNING: linux/time.h: present but cannot be compiled
configure: WARNING: linux/time.h: check for missing prerequisite headers?
configure: WARNING: linux/time.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------ ##
configure: WARNING:     ## Report this to address@hidden ##
configure: WARNING:     ## ------------------------ ##
checking for linux/time.h... yes

If you need any more information feel free to let me know and I'll get back 
to you as soon as I can.
