It may be that the CLIB has badly broken support for 64bit integers on 32
bit platforms. Does anyone know of any Cygwin/Ming issues?
Is this only with the new snprintf code in Win32?
Is this a problem with snprintf as implemented in src/port?
Is there a reason why we don't use the snprintf that comes with the
various C compilers?
