* gv/portable:
  test-lib: use DIFF definition from GIT-BUILD-OPTIONS
  build: propagate $DIFF to scripts
  Makefile: Tru64 portability fix
  Makefile: HP-UX 10.20 portability fixes
  Makefile: HPUX11 portability fixes
  Makefile: SunOS 5.6 portability fix
  inline declaration does not work on AIX
  Allow disabling "inline"
  Some platforms lack socklen_t type
  Make NO_{INET_NTOP,INET_PTON} configured independently
  Makefile: some platforms do not have hstrerror anywhere
  git-compat-util.h: some platforms with mmap() lack MAP_FAILED definition
  test_cmp: do not use "diff -u" on platforms that lack one
  fixup: do not unconditionally disable "diff -u"
  tests: use "test_cmp", not "diff", when verifying the result
  Do not use "diff" found on PATH while building and installing
  enums: omit trailing comma for portability
  Makefile: -lpthread may still be necessary when libc has only pthread stubs
  Rewrite dynamic structure initializations to runtime assignment
  Makefile: pass CPPFLAGS through to fllow customization

Conflicts:
	Makefile
	wt-status.h
