+       tests: do not uselessly require GNU make or gcc in a few tests
+       * tests/lex3.test: Remove gcc from requirements, as any working C
+       compiler should be ok.  Consequently, do not clobber user CFLAGS.
+       Also, remove GNUmake from requirements; it was added (see commit
+       `Release-1-8-103-g0d2f592') because this test fails with FreeBSD
+       make due to VPATH issues -- but so do many other yacc-related and
+       lex-related tests currently, and requiring GNU make in all of
+       them would unacceptably reduce coverage.
+       * tests/lexvpath.test: Remove gcc from requirements, as any
+       working C compiler should be ok.
+       * tests/yacc4.test: Likewise.
+       * tests/yacc8.test: Likewise.
+       * tests/lex5.test: Likewise.  Also, do not require anymore GNU
+       make; to compensate, explicitly call "$MAKE Makefile" to update
+       the out-of-date Makefile if $MAKE is not GNU make.

 +
 +      tests: fix spurious failure in test 'yacc-d-cxx.test'
 +      * tests/yacc-d-cxx.test: Create ylwrap script before calling
 +      automake for the first time, so that the script gets correctly
 +      distributed.  Add checks verifying it indeed is.

 +
 +      tests cosmetics: remove redundant definitions of variable $tab
 +      * tests/yacc-d-basic.test ($tab): Remove definition: it's already
 +      defined in `tests/defs'.
 +      * tests/yacc-d-cxx.test: Likewise.

 +      yacc: add some tests on bison support (still xfailing)
 +      Related to automake bug#7648 and PR automake/491.
 +      * tests/bison-skeleton-cxx.test: New test.
 +      * tests/bison-skeleton.test: New test.
 +      * tests/Makefile.am (TESTS, XFAIL_TESTS): Updated.

 +      * tests/yacc-dist-nobuild-subdir.test: New test.
 +      * tests/Makefile.am (TESTS, XFAIL_TESTS): Update.
