8 Portability problems fixed by Gnulib:
11 @code{volatile sig_atomic_t} is rejected by older compilers on some
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 type @code{pid_t} is not defined on some platforms:
29 The signal @code{SIGPIPE} is not defined on some platforms:
32 The macro @code{SA_NODEFER} is not defined on some platforms:
35 The macros @code{SA_RESETHAND} and @code{SA_RESTART} are not defined
39 The type @code{sighandler_t} (a GNU extension) is not defined on most non-glibc
41 MacOS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, AIX 5.1, HP-UX 11,
42 IRIX 6.5, OSF/1 5.1, Solaris 11 2010-11, Cygwin, mingw, Interix 3.5, BeOS.
45 Portability problems not fixed by Gnulib:
48 Many signals are not defined on some platforms:
51 The macros @code{SIGRTMIN} and @code{SIGRTMAX} expand to an expression of type
52 @code{long} instead of @code{int} on some platforms:
55 The macro @code{SIGBUS} is set to the same value as @code{SIGSEGV},
56 rather than being a distinct signal, on some platforms:
