+
+ * 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
+ the input.at bug reported by Nelson H. F. Beebe in
+ <http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
