Paul Eggert 1be64afa5b 'echo' has some portability problems, when given a first argument ... with a leading '-', or when given any argument containing '\'. Avoid using 'echo' in these cases. * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely. * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise. * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise. * lib/autotest/general.m4 (AT_INIT): Likewise. * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the argument might be unportable. * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise. * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise. * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): (_AC_FC_LIBRARY_LDFLAGS): Likewise. * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise. * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE): (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST): (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise. * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise. * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise. * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): (AC_PROG_MAKE_SET): Likewise. * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER): (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise. * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT): (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED): (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME): (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise. * bin/autoconf.as: Redo verbose flag implementation, as the old scheme wouldn't work with AS_ECHO. * lib/autotest/general.m4 (AT_INIT): Likewise. * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED): Don't use ECHO_T, since ECHO_N is now reliable. * lib/autotest/general.m4 (AT_INIT): Likewise. * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script" rather than using a here-document to put the script into a file. (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can use AS_ECHO. * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise. * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any bug, but we might as well stop using ECHO_N and ECHO_C internally. * lib/autotest/general.m4 (AT_SETUP): Likewise. * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise. * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one operand, as AS_ECHO requires. Avoid double file name expansion. * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE. Don't set as_nl, since _AS_ECHO_PREPARE does that now. (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code. (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros. * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Double-quote strings that would otherwise contain M4 comments. * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.		2006-11-17 21:04:54 +00:00
