                 Key: DAEMON-91
                 URL: http://issues.apache.org/jira/browse/DAEMON-91
             Project: Commons Daemon
          Issue Type: Bug
    Affects Versions: Nightly Builds
         Environment: Linux (arm, hppa, m68k, mips, mipsel, s390, ia64)
            Reporter: Marcus Better


The CPU detection in src/native/unix/support/apsupport.m4 is broken. Based on 
the $host_cpu variable, it tries to guess the operating system. This is 
completely wrong since several operating systems can run on the same 
architecture.

For Debian GNU/Linux we had to apply the following patch. In general, the best 
would be to let autoconf determine the CPU type and not touch it at all, except 
in exceptional cases.
