Not sure this is correct. Even with the first two patches from this
series applied, we have:
dmt:~/git/app/xdm% grep -C3 UNRELIABLE include/dm.h
# if defined(X_NOT_POSIX) || defined(__NetBSD__) && defined(__sparc__)
# if defined(SYSV)
# define SIGNALS_RESET_WHEN_CAUGHT
# define UNRELIABLE_SIGNALS
# endif
# define Setjmp(e) setjmp(e)
# define Longjmp(e,v) longjmp(e,v)
The imake cf files only define X_NOT_POSIX for Apollo and LynxOS
though, and that NetBSD && sparc clause seems to date from xfree86 in
1994, so I think you can be a bit more aggressive here.
Right - on SysV, including SVR4 and even latest Solaris, if you call
signal() to set up handlers you have the problems that the #ifdef
UNRELIABLE_SIGNALS protects against - if you use sigaction() then
you don't. (Effectively SysV signal() is sigaction() with SA_RESETHAND
set in the flags.) We should use POSIX signal handling instead now.
