Bug#347147: kernel-headers-2.6: asm/param.h includes linux/autoconf.h



Package: kernel-headers-2.6
Severity: minor

With this package installed, when you include <sys/params.h> in your
program, you will get a severe namespace pollution since
<linux/autoconf.h> indirectly gets included and it #undefs all sort of
CONFIG_ preprocessor macros (e.g. ELinks using CONFIG_IPV6 macro
internally was affected).

This is not a major bug; Gentoo and Debian Woody don't have the problem
(asm/params.h doesn't include anything), but <sys/params.h> is probably
not standardized anywhere so it's not really specified what exactly
happens when you include it. Still, such a wide collateral damage is
quite unexpected and wastes some time until it gets discovered what went
on...

Possible solution would be to grab CONFIG_HZ information at the package
build time.
