 Portability problems not fixed by Gnulib:
 @itemize
 @item
-@code{struct sigaction} lacks the @code{sa_sigaction} member on some
-platforms; this can also be detected by whether @code{SA_SIGINFO} is defined:
-Interix 3.5.
+Many signals are not defined on some platforms:
+mingw, MSVC 9.
+@item
+The macros @code{SIGRTMIN} and @code{SIGRTMAX} expand to an expression of type
+@code{long} instead of @code{int} on some platforms:
+OSF/1 5.1.
+@item
+The macro @code{SIGBUS} is set to the same value as @code{SIGSEGV},
+rather than being a distinct signal, on some platforms:
+Haiku.
