+       Fix testsuite for ./configure --enable-gcc-warnings:
+       * configure.ac (gcc-warnings): Move -Wall before -Wno-sign-compare.
+       Otherwise, gcc 4.1.0 (at least) warns about sign comparisons in
+       __AT_CHECK_PRINTER_AND_DESTRUCTOR in tests/actions.at.
+       * test/input.at (Torturing the Scanner): #include <stdlib.h> for abort.
+       * test/regression.at (Diagnostic that expects two alternatives):
+       Likewise.
+
 2006-10-12  Paul Eggert  <address@hidden>
 
        * bootstrap.conf (gnulib_modules): Add config-h.
