[tex-k] Re: c-std.h contains declarations which conflict with stdio.h

[Karl Berry]

Hi Frank,

    c-std.h: extern FILE *popen ();
    stdio.h: extern FILE *popen __P ((__const char *__command, __const char *__modes));

Is this a problem?  I had the impression that an empty arg list () was
compatible with a specified arg list.

In any case, there are certainly better ways to handle the problem, like
check specifically for a popen/pclose declaration (AC_CHECK_DECL), and
only declare it in c-std.h if it's not present.  Or, these days,
everything has popen anyway, so just delete the whole thing.

For that matters, lots of stuff in c-std.h looks to have not been
modified in a decade.

However, ultimately any changes in this area are up to Olaf and/or
Thomas ...  I wouldn't want to hack the c-std.h in the TeX Live sources
without their saying the same change will make it back into the master.

Thanks,
karl

Hi Karl,

big spring cleanup in our Debian BTS...

This one has been submitted to Thomas Esser (or rather tetex-pretest)
long ago, but seems to have been lost. I don't currently know of any
problems that it causes, but you should at least be aware of it:

c-std.h: extern FILE *popen ();

stdio.h: extern FILE *popen __P ((__const char *__command, __const char *__modes));

Similar for pclose.

Regards, Frank
