Hi Chris,

Thanks. I probably have an too old version.
Your patch, http://gcc.gnu.org/ml/fortran/2007-01/msg00301.html is not
checked in yet, is it?
I probably should apply the patch first, before continue doing some tests.
Are there further changes or is that patch up to date?

What is actually the procedure for applying patches to the branch?

(We should by the way also merge the trunk up to the branch and
consolidate the VALUE implementation.)

Probably; I try to find my test case - or rewrite it (if I can figure
out what I did).

Regarding to your last patch,
http://gcc.gnu.org/ml/fortran/2007-01/msg00301.html

+ * to generate.         If <code>c_ptr</code> is given, then
<code>c_null_ptr</code>

I think the coding convention is not to use "<code>...</code>"  (at
least none of the other gfortran files do)

+static void gen_special_c_interop_ptrs (const char *kinds[],
+                                       const char *module_name)

If you use

+static void
+gen_special_c_interop_ptrs (const char *kinds[],

one can grep for    ^gen_special_c_interop_ptrs  to find the function
itself (and not the use of the function). This seems to be the coding
convention in gfortran.
