  Modified:    build    apr_common.m4
  Log:
  This is an ugly patch, but fixes a bug when subdir's are actually
  symlinks to the real locations. For example, let's assume we have
  something like this:
  
     $ pwd
     /disk2/jim/src/CVS
     $ ls
     apr         apr-util    httpd-2.0
  
  and httpd-2.0/srclib/apr is actually a symlink to ../../apr. Under
  Solaris, 'sh' (and maybe others) have this behavior:
  
     $ cd httpd-2.0
     $ pwd
     /disk2/jim/src/CVS/httpd-2.0
     $ cd srclib/apr
     $ pwd
     /disk2/jim/src/CVS/apr
  
  Thus, when APR_SUBDIR_CONFIG makes the cache-file pathname relative,
  we point someplace else. Ensuring that cache-file is absolute fixes
  this problem and means there's little restriction on the layouts of
  your httpd-2.0 tree.
