Hi
We are using a code generator for initializing structures with the #define macro. Compiling it with the GCC 2.8.1 (with -ansi) it OK. But when we are using the SUN C 5.0 compiler it screams.
Following is a code sample:
#include <stdlib.h>
#include <stdio.h>

Fatal(3pm) Perl Programmers Reference Guide Fatal(3pm)
NAME
Fatal - replace functions with equivalents which succeed or die
SYNOPSIS
use Fatal qw(open close);
sub juggle { . . . }
import Fatal 'juggle';
DESCRIPTION
"Fatal" provides a way to conveniently replace functions which normally return a false value when they fail with equivalents which raise
exceptions if they are not successful. This lets you use these functions without having to test their return values explicitly on each
call. Exceptions can be caught using "eval{}". See perlfunc and perlvar for details.
The do-or-die equivalents are set up simply by calling Fatal's "import" routine, passing it the names of the functions to be replaced. You
may wrap both user-defined functions and overridable CORE operators (except "exec", "system" which cannot be expressed via prototypes) in
this way.
If the symbol ":void" appears in the import list, then functions named later in that import list raise an exception only when these are
called in void context--that is, when their return values are ignored. For example
use Fatal qw/:void open close/;
# properly checked, so no exception raised on error
if(open(FH, "< /bogotic") {
warn "bogo file, dude: $!";
}
# not checked, so error raises an exception
close FH;
