15 @code{sigset_t} is only declared in <sys/types.h> on some platforms:
18 @code{struct sigaction} and @code{siginfo_t} are missing on some
22 @code{struct sigaction} lacks the @code{sa_sigaction} member on some
24 Irix 5.3, Interix 3.5.
26 The signal @code{SIGPIPE} is not defined on some platforms:

36 Many signals are not defined on some platforms:
39 The macros @code{SIGRTMIN} and @code{SIGRTMAX} expand to an expression of type
40 @code{long} instead of @code{int} on some platforms:
43 The macro @code{SIGBUS} is set to the same value as @code{SIGSEGV},
44 rather than being a distinct signal, on some platforms:
