This sounds much better than the way I've done this. Would the
Makefile.am just include the acpi.c file if HAVE_ACPI is defined and
unconditionally include acpi.h?

Will they? Surely a static inline function returning a single value will
be optimized out? Maybe I have more faith in GCC than I should. ;-)

Thanks for the quick feedback, I'll try doing the conditional
compilation the way you suggest and post a patch back to the list in a
couple of hours.

Disabling some of the probers at compile time is also on my TODO, as
something like the smbios stuff is never going work on the 770 or OLPC.

Richard.
