I kept the SAVE attribute because the comment (which you remove
in your patch) claims that it is needed to actually allow the 
the compiler to initialize c_null_ptr and c_null_funptr to NULL.
I did not go through the code to validate the comment's claim.

I did not use is_iso_c because I forgot about its existence.
If your patch passes regression testing, go ahead and commit it.
