-        Convert a variable to type decimal to an integer.
+        Convert a variable of type decimal to an integer.
While related, this should be committed and backpatched regardless.

+       int                     errnum = 0;
Stylistic nit, we typically don't initialize a variable which cannot be
accessed before being set.

Overall the patch looks sane, please register it for the next commitfest to
make it's not missed.
