FreeBSD's shell permits [^bar] to match characters not in [bar] like common regular expressions. This is non-portable and '!' should be used in place of '^' for portability.

# A number of header files in sys/* have, going back to 7th Edition Unix in
|
|
# 1979, reqiured other files (like sys/types.h) to compile. Likewise the 4BSD
|
|
# networking code has had prerequisites. However, going back to around the turn
|
|
# of the century, other systems have made them be independently includable
|
|
# (wide-spread header include protection post-dates 7th edition Unix by maybe 4
|
|
# or 5 years judging from netnews sources). Start down the path of making them
|
|
# all independently includable by creating this test that fails buildworld when
|
|
# they are not.
|
|
#
|
|
# The _foo.h files are excluded as they are internal-only headers and/or have
|
|
# special requirements. Since the purpose of this is to allow autoconfig
|
|
# programs to detect FreeBSD has different headers, omitting internal
|
|
# headers cuts down on the noise w/o causing problems for the goal.
