This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU Automake".

commit 405477b5a2ea6d79c30255db14dbb59b84495fb7
Merge: 4cffe41 3544a43
Author: Stefano Lattarini <address@hidden>
Date: Sun Jan 9 16:20:34 2011 +0100
Merge branch 'yacc-work'
commit 3544a43c4923f767467536d02abb511d7e04ab2c
Author: Stefano Lattarini <address@hidden>
Date: Fri Jan 7 21:52:56 2011 +0100
yacc: support variable expansions in *YFLAGS definition.
This change fixes automake bug#7800.
* automake.in (lang_yacc_target_hook): Use 'value_as_list_recursive'
instead of 'variable_value' to get the value of *YFLAGS variables.
Related changes.
($DASH_D_PATTERN): Removed.
* tests/Makefile.am (XFAIL_TESTS): Remove yflags-var-expand.test.
* tests/yacc-clean.test: Remove workaround for now-fixed bug.
* NEWS: Update.
commit eb7adcd2b2911e26792000bc89e09894b182f323
Author: Stefano Lattarini <address@hidden>
Date: Fri Jan 7 20:52:17 2011 +0100
yacc: more tests on *YFLAGS support
* tests/yflags-var-expand.test: New test, still xfailing. It
exposes automake bug#7800 -- "automake fails to honor `-d' in
AM_YFLAGS when variable expansions are involved".
* tests/yflags-d-false-positive.test: New test, checking that
automake do not spuriously see `-d' in *YFLAGS when that isn't
really there.
* tests/yflags-force-override.test: New test, checking that
automake can cope with definition of the YFLAGS variable in
Makefile.am (even if that is an extremely bad practice, as that
variable is user-reserved).
* tests/yflags-cmdline-override.test: New test, checking that
automake can cope with user-redefinition of YFLAGS at configure
time and/or at make time.
* tests/yflags-conditional.test: New test, checks that automake
warns on conditionally-defined *YFLAGS variables.
* tests/Makefile.am (TESTS, XFAIL_TESTS): Update.
commit c5b255bacb70ccb09b923f1a5acb4e6abca88385
Author: Stefano Lattarini <address@hidden>
Date: Wed Jan 5 16:07:56 2011 +0100
yacc: extend and improve tests
* tests/yacc-basic.test: Also check that the intermediate C file
is mentioned in the generated Makefile.in, and that it is created
by the first make invocation.
* tests/yacc3.test: Test removed, superseded by ...
* tests/yacc-d-basic.test: ... this new test.
* tests/yacc2.test: Add reference to that new test in the heading
comments.
* tests/yacc-d-vpath.test: New test.
* tests/yaccvpath.test: Updated heading comments. Do not require
gcc anymore, as any working C compiler should be enough. Remove
redundant comments.
* tests/yacc-nodist.test: New test.
* tests/yacc-dist-nobuild.test: New test.
* tests/Makefile.am (TESTS): Update.
