in reply to What is __need___va_list, and do I need it?

h2ph is passe and it became passe because it had problems. I suspect that your /usr/include/stdarg.h contains:

#define __need__va_list 1 /*or something*/ ... #undef __need__va_list
and h2ph just translates it into some Perl approximation of the same thing and does it in a way that isn't clean when warnings are enabled (perhaps that warning was added after h2ph stopped being actively maintained).

It would probably be pretty easy for you as a human (and thus being much smarter than the h2ph script) to clean up stdarg.ph to make it not emit any warnings. Avoiding new uses of h2ph and *.ph files would also be a good idea, BTW (though I'm not implying any judgement on what you are currently doing).

    I've done a little more investigating and have found that the warning is being generated by my use of this line -
    use Sys::Syslog qw(:DEFAULT setlogsock);

    The relevant line in the stdarg.ph file is -
     undef(&__need___va_list) if defined(&__need___va_list);

    And in /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/include/stdarg.h there are the two lines that you suggested would be there.

    a's post is interesting too, seeing as the eventual target platform for the program is Solaris... I'll get in touch with the client on Monday and find out if they get the same problem, or whether they've resolved it in the way you suggest (tidying up the stdarg.ph).

    Thanks very much for the responses :0)
