   _gfortran_transfer_real128;
   _gfortran_transfer_real128_write;
#endif

That would also work for me.

or make that dependent on HAVE_GFC_REAL_17 or whatever else (with suitable
includes that only define macros and not actual C code).

With my most recent commit, HAVE_GFC_REAL_17 can now be found in
kinds.inc if all of the macros above are defined, that should
be suitable.

I found that __powerpc64__ is not defined when compiling *.F90 files
(which is why I added them by hand). Not sure how the preprocessor is
invoked on gfortran.map, but if things don't work, this could be
related :-)

So, it's OK either way with me.  What do others think?
