Since PDL_Long * pos is the RETVAL

I don't think so.
That //code... stuff specifies SET_RETVAL_NV(x); which I think does *not* set pos to the RETVAL.
Afaik at no stage does a 'PDL_Long *' get passed from perl to XS (or vice-versa) which is precisely why there should be no need for any typemap entry for 'PDL_Long *'.

I also find that it doesn't matter whether the typemap has: 
PDL_Long * T_PTR

[download]
or 
PDL_Long * T_FOO

[download]
I suspect you could specify just about anything.

And why would we need this typemap entry only with ExtUtils-ParseXS-3.0x ?
Even perl-5.14.1 ships with version 2.2210 - and it doesn't require any typemap entry.

I would test it, but, PDL takes a while to compile

Like I said, it doesn't take long to hit the error - about 1 minute into the 'make' stage is all it takes to find out what works and what doesn't. The thing that takes most time is the running of 'make realclean' between successive attempts :-)

Cheers,
Rob
