+       * data/glr.c (yyFail): Always set yyerrflag.  Corrects regression

+       * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
+       "$CC -E foo.h" is allowed, as this doesn't work with the Portland
+       Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
+       file twice in the grammar, as an extra check.
+
+       * tests/input.at (Torturing the Scanner): Surround the
+       backslash-newline tests with "#if 0", to make it less likely that
+       we'll run into compiler bugs.  Bring back solitary \ inside
+       comment, but add a closing comment to work around HP C bug.  Don't
+       test backslash-newline in C character constant.  This should fix
