[alsa-devel] [PATCH] autoconf problems

Dear List,
A month ago I was having trouble building alsa-drivers on RHEL5.
The following patch fixes the problems.
The root of the problem is that including the header
include/linux/config.h produces a warning on RHEL5. This interferes with
several autoconf tests that treat warnings as errors. Therefore it seemed
best to globally check use of
#include <linux/config.h>
in the same pattern as was already done for init_utsname.
Furthermore, the check for is_power_of_2 would produce 2 warnings: one for
the use of an undeclared function (desired), and another warning for an
un-used variable. Still the test would succeed, because the required
condition is flagged by warnings, not errors. This was fixed by following
the pattern from init_utsname.
