Change Details

A number of header files in sys/* have, going back to 7th Edition Unix, reqiured other files (like sys/types.h) to compile. However, going back to around the turn of the century, other systems have made them be independently includable. Start down the path of making them all independently includable by creating this test that fails buildworld when they are not. Currently, this is one big ugly list. That's unavoidable as less than half of the sys/* files are independent. Sponsored by: Netflix

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 file 'goodfiles.inc' contains a list of the currently working files that can be included w/o any prerequisites. As files are fixed, 'make goodfiles.inc' should be re-run to regenerate the list. That target should never be run when files have broken.
