8 Portability problems fixed by Gnulib:
11 @code{volatile sig_atomic_t} is rejected by older compilers on some
15 @code{sigset_t} is missing on some platforms:
18 @code{sigset_t} is only declared in <sys/types.h> on some platforms:
21 @code{struct sigaction} and @code{siginfo_t} are missing on some
25 @code{struct sigaction} lacks the @code{sa_sigaction} member on some
27 Irix 5.3, Interix 3.5.
29 The type @code{pid_t} is not defined on some platforms:
32 The signal @code{SIGPIPE} is not defined on some platforms:
35 The macro @code{SA_NODEFER} is not defined on some platforms:
38 The macros @code{SA_RESETHAND} and @code{SA_RESTART} are not defined
42 The type @code{sighandler_t} (a GNU extension) is not defined on most non-glibc
44 Mac OS X 10.5, FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, AIX 5.1, HP-UX 11,
45 IRIX 6.5, OSF/1 5.1, Solaris 11 2011-11, Cygwin, mingw, MSVC 9, Interix 3.5, BeOS.
48 Portability problems not fixed by Gnulib:
51 Many signals are not defined on some platforms:
54 The macros @code{SIGRTMIN} and @code{SIGRTMAX} expand to an expression of type
55 @code{long} instead of @code{int} on some platforms:
58 The macro @code{SIGBUS} is set to the same value as @code{SIGSEGV},
59 rather than being a distinct signal, on some platforms:
