Before you apply this patch, I would also like to know what precisely
goes wrong on this version of MacOS X. Currently, all we have is hearsay:
- On one hand, the snprintfv code from 2004 suggesting that MacOS X <wchar.h>
exists but needs <runetype.h>,
- On the other hand, I remember that on MacOS X 10.2 autoconf recognized
<wchar.h> as absent - but I don't remember whether I found it actually
missing in /usr/include/.
- In source code of MacOS X from http://www.opensource.apple.com/darwinsource/
(take the 'Libc' packages) you see that MacOS X 10.0.4, 10.1.5, 10.2.8
did not have a <wchar.h> but that MacOS X 10.3 has a <wchar.h> that
appears to be missing nothing when compared to <runetype.h>.
