2.5.1 only the last one is honored:
> echo "foonbar" | egrep -e 'foo' -e 'bar'
bar
> echo "foonbar" | egrep -e 'bar' -e 'foo'
foo

An alternative would have to use `sed', unfortunately alternation
is not portable.
* tests/actest.m4 (join): New macro.
(AC_ENV_SAVE): Join the egrep patterns into a single big one.
* tests/Makefile.am (EGREP_EXCLUDE): Rename as FILTER_MACROS.
Join the egrep patterns into a single big one.
* acgeneral.m4 (AC_CHECK_MEMBER): It is not smart to define
ac_Foo, and use AC_Foo. Got rid of AC_Member_Aggregate and
AC_Member_Member which were complicating more than simplifying.
(AC_CHECK_DECLS): Use m4 lists.
(AC_CHECK_TYPES): A comma was missing.
* autoheader.m4: (AC_CHECK_DECLS): Use m4 lists.
* doc/autoconf.texi (Generic Declarations): AC_CHECK_DELCS uses m4
lists.
* tests/semantics.m4: New file. Collection of semantical tests:
verify that the tests are positive and negative when appropriate.
Test AC_CHECK_MEMBERS, AC_CHECK_DECLS and AC_CHECK_TYPES.
Introduce a new style of testing, independent from DejaGNU.
Introduce the logistics.
* configure.in: Initialize AT, and output tests/atconfig, and
tests/Makefile.
* m4/atconfig.m4: New file.
* m4/Makefile.am: Adjusted.
* aclocal.m4: Include atconfig.m4.
* Makefile.am: Adjusted.
* tests/Makefile.am: New file.
* tests/atgeneral.m4: Likewise.
* tests/atconfig.in: Likewise.
Write tests.
* tests/syntax.m4: New file, in charge of checking the validity of
the sh code produced by the macros defined in acspecific.m4.
acgeneral.m4 is not checked here, because these macros require
arguments.
* tests/suite.m4: New file. Run syntax.m4.
New version of AC_INCLUDE, which does not glob, nor rely upon the
shell. Add AC_INCLUDES too. Help tracking multiple inclusions.
* acgeneral.m4 (m4_errprint, m4_warn, m4_fatal): New macros,
variations around errprint.
(m4_include_unique): New macro which registers what are the files
already included, and warns if some are included several times.
(m4_include, m4_sinclude): New macro, using m4_include_unique.
(AC_INCLUDE): Is now just a wrapper of m4_include.
(AC_INIT): Use m4_sinclude, not sinclude.
(_AC_ERRPRINT): Removed, m4_errprint is here!
(AC_WARNING, AC_FATAL): Wrappers of m4_warn and m4_fatal.
Create man pages for the executables.
* Makefile.am (SUBDIRS): Add `man' and prepend `.' so that
executables be built before help2man is run.
* configure.in (AC_OUTPUT): Add man/Makefile.
AC_MSG_ERROR, not AC_ERROR.
Check for missing help2man.
* man/Makefile.am: New file.
* man/autoconf.x: Likewise.
* man/autoreconf.x: Likewise.
* man/autoheader.x: Likewise.
* man/autoscan.x: Likewise.
* man/autoupdate.x: Likewise.
* man/ifnames.x: Likewise.
