 # Add --enable-maintainer-mode option to configure.  # AM_PROG_INSTALL_STRIP
 # From Jim Meyering  # ---------------------
   # One issue with vendor `install' (even GNU) is that you can't
   # specify the program used to strip binaries.  This is especially
   # annoying in cross-compiling environments, where the build's strip
   # is unlikely to handle the host's binaries.
   # Fortunately install-sh will honor a STRIPPROG variable, so we
   # always use install-sh in `make install-strip', and initialize
   # STRIPPROG with the value of the STRIP variable (set by the user).
   AC_DEFUN([AM_PROG_INSTALL_STRIP],
   [AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
   # Installed binaries are usually stripped using `strip' when the user
   # run `make install-strip'.  However `strip' might not be the right
   # tool to use in cross-compilation environments, therefore Automake
   # will honor the `STRIP' environment variable to overrule this program.
   dnl Don't test for $cross_compiling = yes, because it might be `maybe'.
