There's a difference between obsolete compliance (and yes, Paul is right
that C compilers that required signal handlers with return type of int
were implicitly made obsolete 19 years ago when C89 was standardized) and
While C compilers may have originally had something to do with
returning 'int' rather than 'void' that was not even still the case
when POSIX.1 was ratified since virtually all compilers current at
that time supported 'void', 'const', and prototypes. The cause at
that time was that the systems were already using 'int' and so system
headers said 'int'. Changing it was a big deal for the users since
they would have to change their code. POSIX.1 and ANSI C were
ratified fairly close in time. I recall having to deal with this
issue on fairly recent systems in the 1996-98 timeframe so 'int'
didn't just go away because ANSI C said so. The switch took place
after the next raft of POSIX standard updates around 1996 or so.
Even C99 is taking a long time to become deployed, partly because GCC
is not helping as much as it should be by refusing to add update
headers like stdint.h to existing systems.
I am saddened that it seems that Paul has gone to the dark side ...
