Subject: - Changed the main core of system include files to use the same "#if"
X-Git-Url: https://mattmccutchen.net/rsync/rsync.git/commitdiff_plain/e95538ca2c8fdecd66a112635aa30077419af685

- Changed the main core of system include files to use the same "#if"
  idioms that configure uses.
- Use "#if" (not "#ifdef") for configure-defined macros.
- Use "#if !" (not "#ifndef") for configure-defined macros.
