Present but not compiled headers

[David McCabe]

I'm getting output such as this from Gentoo 2004.0:

checking linux/time.h usability... no
checking 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

This comes from xinetd's configurater.
Errors such as this have also happened with XShm.h, in tuxnes.
This is with autoconf 2.58.

Thanks!
