It's probably a compiler issue, not an OS issue; if you were using GCC on
Windows, with the -Werror=c++-compat flag, you'd get the same warning, and if
you were using a vendor C compiler (Oracle Studio, HP aCC, IBM XL C, etc.), you
might not get that warning.

Yes, as Evan noted, you need a "pointer to a pointer" (gpointer *) as the
second and third arguments.

gtp_info would have to be a *pointer* to a struct, so that >p_info would be a
pointer to a pointer, and you'd cast it to "gpointer *" rather than to
"gpointer". g_hash_table_iter_next() would set that pointer to point to the
key of the next entry it finds in the hash table.
I don't know what the values are in your hash table, guint32 or pointer to
guint32, and the way you'd fix that one would depend on the type.
