[MXE mingw] "unknown type name 'int64_t'" with --enable-64 when compiling mex files

[Philip Nienhuis]

While trying to install the io package on a MXE-cross-built Octave with
--enable64, I get the following error messages:

:
mkoctfile --mex __num2char__.c
In file included from
C:\Octave\octave64-3.8.2\include\octave-3.8.2\octave/mexproto.h:71:0,
                 from

                 from __num2char__.c:16:
C:\Octave\octave64-3.8.2\include\octave-3.8.2\octave/mxarray.h:89:9: error:

         ^

mkoctfile could compile the "regular" .oct files fine and they work fine as
well (compiled individually). It is just the two mex files that give errors.
So, AFAIU 'int64_t' doesn't seem to be defined; I grepped around in
<octave>/include/ but couldn't find out where the definition is.
It has something to do with MXE or Mingw; because on my Linux 64bit box, the
io package installs (and works) fine in Octave built with --enable-64.

Any suggestions or fixes?

Thanks,

Philip
