  dnl  *automake 1.4 install-strip sets A_M_INSTALL_PROGRAM_FLAGS to -s
  dnl   and has INSTALL_PROGRAM = @INSTALL_PROGRAM@ $(A_M_INSTALL_PROGRAM_FLAGS)
  dnl   it header-vars.am, so there the actual INSTALL_PROGRAM gets the -s
  dnl  *automake 1.4a (and above) use INSTALL_STRIP_FLAG and only has
  dnl   INSTALL_PROGRAM = @INSTALL_PROGRAM@ there, but changes the
  dnl   install-@DIR@PROGRAMS targets to explicitly use that flag
  dnl  *autoconf 2.13 is dumb, and thinks it can use INSTALL_PROGRAM as
  dnl   INSTALL_SCRIPT, which breaks with automake <= 1.4
  dnl  *autoconf >2.13 (since 10.Apr 1999) has not that failure
  dnl  *sometimes KDE does not use the install-@DIR@PROGRAM targets from
  dnl   automake (due to broken Makefile.am or whatever) to install programs,
  dnl   and so does not see the -s flag in automake > 1.4
  dnl to clean up that mess we:
  dnl  +set INSTALL_PROGRAM to use INSTALL_STRIP_FLAG
  dnl   which cleans KDE's program with automake > 1.4;
  dnl  +set INSTALL_SCRIPT to only use INSTALL, to clean up autoconf's problems
  dnl   with automake<=1.4
  dnl  note that dues to this sometimes two '-s' flags are used (if KDE
  dnl   properly uses install-@DIR@PROGRAMS, but I don't care
