Hi,

I am no fan of redefining/open coding things which reasonable can be
expected to be provided through normal GNU system headers/libs. But
these seem fairly minor. However if there are larger changes needed we
should probably pull in the relevant gnulib modules.

I added ChangeLog entries and moved the powerof2 redefinition to
system.h since that is included by all files that use it. Does the
attached patch work on your setup?

Thanks,

Mark
