/* 
  This piece of code will trigger the warning "passing arg 1 of `name' from 
  incompatible pointer type" on lines 24, 25 and 26, but it should not, 
  because the pointers are in fact compatible. To prove the compatibility 
  comment out the "[8]" at line 9 and recompile; the warnings will disappear. 
  The warnings also disappear if the "const" from the OSHSAddrToBinIPv4() 
  declaration is removed; I guess that the "const" is doing problems.

/* 
  - Tested with gcc 3.2.2 on Mandrake GNU/Linux 9.1 ("bamboo") 
    (kernel 2.4.21-0.13mdk) on an i686 
  - Fails also with gcc 3.5.0 (experimental 17072004) on the same machine 
  - There is no bug when pointers to a structure or union are involved.
