-@item -Wno-pointer-sign
-In version 4.0, GCC began warning about pointer argument passing or
-assignment even when the source and destination differed only in
-signedness. However, most @value{GDBN} code doesn't distinguish
-carefully between @code{char} and @code{unsigned char}. In early 2006

+@item -Wpointer-sign
+This helps make sure @value{GDBN} code uses @code{gdb_byte} which is
+really @code{unsigned char} for raw bytes instead of @code{char},
+whose signness is host-dependent. @sc{gcc} enables this with
+@code{-Wall} since version 4.0. We enable it explicitly too to be
+decoupled from future @sc{gcc} (or other compiler)'s defaults.

Due to the way that @value{GDBN} is implemented many functions have
