use yes/no instead of true/false in confgure scripts * acinclude.m4 (OCTAVE_CHECK_LIB, OCTAVE_ENABLE_READLINE, OCTAVE_PROG_TEXI2PDF): Use yes/no instead of true/false for consistency with autoconf macros. (OCTAVE_PROG_TEXI2PDF): Rename ac_octave_missing to ac_texi2pdf_missing. * configure.ac (BOUNDS_CHECKING, USE_OCTAVE_ALLOCATOR, USE_ATOMIC_REFCOUNT, USE_64_BIT_IDX_T, USE_OPENMP, F77_TOLOWER, F77_APPEND_UNDERSCORE, F77_APPEND_EXTRA_UNDERSCORE, build_jit, INCLUDE_DEPS, build_fftw_threads, native_graphics, check_opengl, SHARED_LIBS, STATIC_LIBS, ENABLE_DYNAMIC_LINKING, NO_OCT_FILE_STRIP, BUILD_COMPILED_AUX_PROGRAMS, link_all_deps, dlopen_api, shl_load_api, loadlibrary_api, dyld_api, try_extra_warning_flags, try_strict_warning_flags, build_java, have_jni): Use yes/no instead of true/false for consistency with autoconf macros. * liboctave/cruft/mk77def.in (F77_TOLOWER, F77_APPEND_UNDERSCORE, F77_APPEND_EXTRA_UNDERSCORE): Use yes/no instead of true false.
