 libiconv defines the second parameter of the iconv function differently on
 different operating systems. Specifically libiconv tries to mimic the
 behavior of the system's iconv, whatever that may be. The author of
 libiconv [http://lists.gnu.org/archive/html/bug-gnu-
 libiconv/2008-06/msg00001.html appears to intend] this behavior.

 However libiconv in MacPorts seems to have some peculiarities of its own
 in how and when that function's definition changes.

 In ${prefix}/include/iconv.h we see the different definitions of the iconv
 function.

 MacBook Pro Core 2 Duo, Tiger[[br]]
 libiconv @1.12_2 (non-universal):

 {{{
 extern size_t iconv (iconv_t cd, const char* * inbuf, size_t *inbytesleft,
 char* * outbuf, size_t *outbytesleft);
 }}}

 MacBook Pro Core 2 Duo, Tiger[[br]]
 libiconv @1.12_2+darwin_8+universal (4-arch) before r46078 / using
 MacPorts built-in universal variant:

 {{{
 extern size_t iconv (iconv_t cd,  char* * inbuf, size_t *inbytesleft,
 char* * outbuf, size_t *outbytesleft);
 }}}

 MacBook Pro Core 2 Duo, Tiger[[br]]
 libiconv @1.12_2+universal (4-arch) after r46078 / using muniversal
 portgroup:

 {{{
 #ifndef __LP64__
 extern size_t iconv (iconv_t cd, const char* * inbuf, size_t *inbytesleft,
 char* * outbuf, size_t *outbytesleft);
 #else /* __LP64__ */
 extern size_t iconv (iconv_t cd,  char* * inbuf, size_t *inbytesleft,
 char* * outbuf, size_t *outbytesleft);
 #endif /* __LP64__ */
 }}}

 I'm not certain why the function is different on 32-bit an 64-bit.
