AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the

`missing' itself contains variables.

Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
obsoleted, and redirect to the former anyway.

processed only if present.
* tests/torture.at (Configuring subdirectories): Use autoreconf
instead of successive calls to autoconf.
Add a nonexistent subdirectory to exercise the patch above.
Reported by Ralf Corsepius.
(&file_name_is_absolute): New, wrappers around routines from
File::Spec.
Use and export them.
(&find_configure_ac): Optionally take a directory where to look at.
* bin/autoreconf.in (&parse_args): Trim the configure.ac part of
the arguments.
Default @ARGV to `.', not find_configure_ac.
(&autoreconf): Argument is a directory.
Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
* doc/autoconf.texi (autoreconf Invocation): Update.
(@export_forward_subs): New.
Add basename, dirname, and fileparse.
(@EXPORT): Adjust.
* bin/autoreconf.in (&autoreconf): Fix call to fileparse.
Don't look for aclocal flags if we already know aclocal is not
used.
Move aclocal.m4t only if it exists.

(&maybe_autoreconf, File::Find): Remove, unused.
(&autoreconf): If autoconf is not used, don't try to trace.
invoking AS_BASENAME. Set the locale variables to 'C' if
possible, as POSIX requires this to get the traditional
behavior.
* doc/autoconf.texi (Special Shell Variables): Describe the above.
Awk. Fix the sed prepass to work even if there are multiple
instances of $LINENO on the same line. Do not substitute for
other variables like $LINENOT. Do not check file dates; such a
check is unreliable on sufficiently fast machines, and removing
the check makes the code simpler and more reliable. Check for
output and chmod failures.

lib/Autom4te/Struct.pm:
Require Perl 5.005_03 instead of just 5.005, as some tests fail
with 5.005_02.
* doc/autoconf.texi (Special Shell Variables): Document some
more LINENO gotchas, particularly with respect to the Awk+Sed hack.
* lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
(_AS_LINENO_PREPARE): Use it instead of shell eval, since
eval $LINENO is not portable in practice.
