Subject: - Move tests for constants defined in O.S. headers into osdep.h - test
X-Git-Tag: V2-BETA-1-PATCH-14~6
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=5b4fcc905f32ee91f9a66c2db7b80b9eea0c445e;p=thirdparty%2Fdhcp.git

- Move tests for constants defined in O.S. headers into osdep.h - test
  for HAVE_whatever in .c files.   Define relevant HAVE_whatevers in
  linux.h, so that versions of linux that define these constants as
  enums will still work.
