Release Notes for BSDBuild 3.0
------------------------------
- It is now possible to control conditional compilation from configure
  (i.e., a Makefile's ${SRCS} definition may safely reference configure-
  script-defined variables). To accomodate this, when using separate builds,
  mkconcurrent is now invoked at the very end of configure (and it performs
  more extensive parsing of Makefiles as well).
- New mkconfigure(1) directives: MAPPEND(), CHECK_PERL_MODULE(), DEFAULT_DIR().
- Prevent redundant Makefile.config definitions from being produced.
- Avoid using system the libtool if it is not GNU libtool.
- Added --moduledir, --statedir and --libexecdir (and others for GNU compat).
- mkconfigure(1) now processes long line breaks on input scripts.
- Added macros to simplify Emul() handling, removed unneeded Emul() code.
- Renamed ${SHAREDIR} -> ${DATADIR} and ${SHARE} -> ${DATAFILES}.
- Compiler attribute tests have been moved to a separate module cc_attributes.
- mkdep(1) now passes any "-m" cflags to the compiler.
- build.prog.mk(5) and build.lib.mk(5) now honor ${OBJC}.
- build.proj.mk(5) now accepts more specific "windows-foo" targets.
- All modules should now honor ${DESTDIR}.
- New tests: objc, gcc, getpwnam_r, gethostbyname, portaudio, mysql, cocoa,
  sockopts, crypt, winsock, siocgifconf, fontconfig
