2dd55767bSWarner Losh# A number of header files in sys/* have, going back to 7th Edition Unix in
3dd55767bSWarner Losh# 1979, reqiured other files (like sys/types.h) to compile. Likewise the 4BSD
4dd55767bSWarner Losh# networking code has had prerequisites. However, going back to around the turn
5dd55767bSWarner Losh# of the century, other systems have made them be independently includable
6dd55767bSWarner Losh# (wide-spread header include protection post-dates 7th edition Unix by maybe 4
7dd55767bSWarner Losh# or 5 years judging from netnews sources). Start down the path of making them
8dd55767bSWarner Losh# all independently includable by creating this test that fails buildworld when
9dd55767bSWarner Losh# they are not.

11dd55767bSWarner Losh# The _foo.h files are excluded as they are internal-only headers and/or have
12dd55767bSWarner Losh# special requirements. Since the purpose of this is to allow autoconfig
13dd55767bSWarner Losh# programs to detect FreeBSD has different headers, omitting internal
14dd55767bSWarner Losh# headers cuts down on the noise w/o causing problems for the goal.
