* NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
* doc/autoconf.texi (Special Chars in Variables): New section.
(Preset Output Variables): Warn about special chars in CPPFLAGS.
(Installation Directory Variables): Quote $(datadir) better.
(Limitations of Builtins): Describe some of eval's trickiness.
* lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
* lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
in front of every arg, not just trailing args. Quote apostrophes.
(_AC_EVAL_ECHO): New macro.
(_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
(AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
removed.
(_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
exposed by quoting of eval argument. Put the command on line line
so it logs better.
* lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
(_AC_PATH_X, AC_PATH_X): Quote more safely.
* lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
* lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
* lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
Handle special chars in prefix, ac_srcdir, ac_aux_dir.
Use eval more safely.
(_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
* lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
to be replaced.
* tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
lines, exposed by quoting of eval argument.
