in URLs to improve DVI formatted output (requires texinfo 4.6).
(System Services, Systemology, Shellology): Likewise.
(Limitations of Usual Tools): Rewrite Mac OS X example for nicer
output.
(Integer Overflow, Null Pointers, Buffer Overruns):
(Floating Point Portability, Exiting Portably): New sections.
(Writing Test Programs): Fix some langauge. Recommend exiting
with status 1, not merely nonzero. Clarify exit declaration.
(Run Time): Move C exit status stuff to new Exiting Portably section.
(Systemology): Mention Posix and levenez. Update v7 reference.
(Portable Shell): Mention the Posix shell.
* doc/autoconf.texi (Programming in M4sh): Comment out the
documentation of AS_BASENAME, for now.
(Shell Substitutions): Do not use AS_DIRNAME in an example.
(Limitations of Builtins) <basename>: Do not refer to
AS_BASENAME.
* bin/autoconf.as (me): Don't use AS_BASENAME.
(dir): Remove the unused variable.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
(AS_BASENAME): Use "basename --" to protect against leading "-".
(_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
(_AS_DIRNAME_PREPARE): Likewise.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
(AS_DIRNAME): Use "dirname --".
of "run time" and "run-time" changed to "runtime", for consistency.
* lib/autoconf/fortran.m4: Likewise (in comment).
* lib/autoconf/functions.m4: Likewise.
* lib/autoconf/general.m4: Likewise.
* lib/autoconf/headers.m4: Likewise.
* doc/autoconf.texi (Programming in M4sh): Remove mention of
AS_VAR_SET_BASENAME, AS_VAR_SET_DIRNAME, and AS_BASENAME.
We have to keep AS_DIRNAME since it was part of a stable Autoconf,
but AS_BASENAME doesn't have to be supported.
AS_VAR_SET_DIRNAME and AS_VAR_SET_BASENAME.
* doc/autoconf.texi (Programming in M4sh): Document this. All uses
changed. The newer interfaces are more reliable, as they allow
implementations that handle trailing newline correctly. For now,
we're in a freeze, so I did not include the more-reliable
implementations, but I wanted to correct the interface before 2.60
goes out.
* lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
AS_DETECT_REQUIRED. All uses changed.
(_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
All uses changed.
(_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

(_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
(_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".

(_AS_DIRNAME): Renamed from AS_DIRNAME. All uses changed.
(_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
(_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
Use "dirname --".
(AS_VAR_SET_BASENAME, AS_VAR_SET_DIRNAME): New macros.
* tests/m4sh.at (AS_VAR_SET_DIRNAME): Renamed from AS_DIRNAME.
Test the new API. Don't test internals, since they're probably
going to change anyway.
(AS_VAR_SET_BASENAME): Likewise, renamed from AS_BASENAME.
* bin/autoconf.as: Don't use AS_BASENAME or AS_DIRNAME. This
removes a bootstrapping problem with the changes described above.
The AS_DIRNAME part wasn't used, anyway, and the AS_BASENAME
part can be done portably without all the deep Autoconf magic.
top-level tests after micro-suite has been run. Used in...
(Debugging a successful test, Debugging script and environment),
(Debugging a failed test): ...these new tests. The first of these
is fixed by...
* lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
macro, split out from...
(AT_INIT): ...here, so that using -d also generates a run script.
Document that -d inhibits top-level logging.
* doc/autoconf.texi (testsuite Invocation): Document that -d only
inhibits top-level logging; debug scripts are created.
* lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
and DUALCASE=1.
(AS_SHELL_SANITIZE): Remove DUALCASE=1.
* doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
it is set.
Give an example for AS_DIRNAME instead of referring to Posix..
(File System Conventions): Put discussion of // versus / here, and
modernize it a bit.
(Limitations of Usual Tools): Add basename. Remove verbiage
after dirname, since it got moved to the above sections.
All this was inspired by a patch proposed earlier by Ralf Wildenhues.
`@setcontentsaftertitlepage' for HTML.
(Writing Autoconf Macros): Likewise, insert space after `@c'.
(Leviticus, Numbers, Deuteronomy): Likewise, change `@,c' to
`@,{c}'.
`expr' away if there is nothing to do.
< --keywords >: Simplify and robustify argument handling.
Revert erroneous comment from 2005-08-23. Extend to allow
keyword negation with `!'.
Update help message. Remove broken code to prevent running
tests multiple times.
* doc/autoconf.texi (testsuite Invocation) < --keywords >:
Update and fix the documentation accordingly.
* tests/autotest.at (Keywords): Renamed to..
(Keywords and ranges): .. this. Extended to make sure negated
keywords, keywords taken from AT_SETUP arguments, and numeric
test ranges work, and that matching is case-insensitive.
