libiconv anyone ?

[John Emmas]

Recently I've been trying to find a library called "iconv" (it's needed 
by libxml I believe).  Many years ago I obtained a pre-built 'dev' 
version when building libxml for Win32 (i.e. the dev version offers 
Dll's + libs + header files).  But I can't seem to find a Win64 version 
anywhere and I've been told it's now part of libc.

Is that correct?  And if so, can I obtain a Win64 'dev' version?  Or is 
it only buildable from source these days?  Many thanks,
