i noticed that up till now, it has built everywhere but
- - linux/mips (scheduled)
- - hurd (scheduled)
- - kfreebsd (failed)
i expect the hurd build to fail as well, due to the same problem as the
kfreebsd builds: the filename extension for the external (module) is not
this can be easily fixed, by forcing a certain extension via configure
flags (which i have just pushed).
the "puredata" package uses the "pd_linux" extension for all externals
on Debian, so i just used that (even though it might seem uncorrect to
use the "linux" extension on a hurd or freebsd kernel).

i never really understood what to use for pointers in fprintf.
anyhow, in the given function it is save to cast to uint, as it is only
for pretty printing...

i think the problem is more on x86_64 where the pointer is has the same
size as "long int"

i think upstream will be switching to autoconf/automake which should fix

the configure script does a test whether the compiler supports the
sse-flags. i think this is the case with modern gcc on x86 regardless of
the cpu used, so this might become a problem.
honestly, in the meantime i would wait till somebody complains (either a
user or the policy police) or the policy changes...
the fix shouldn't be too complicated to do (needs a patch against
on other platforms (not x86 and x86_64) the flags should be no problems
(since they are not used)

the fPIC flag is tested for during configure time, and it's only used if
the compiler supports it.
it was introduced, because x86_64 does require it.
it can be turned off by using "--disable-PIC", though of course this has
to exclude x86_64
