Subject: [PATCH] avoid naming local function as one of printf family

Fixes build issues with clang
error: no member named '__builtin___snprintf_chk' in 'struct expr_ops'

Use wiggle to get the patch to apply for version 1.2.0.

Add the same change in src/expr/last.c to make the patch apply for
1.2.1. Also correct the patch to show the original author and metadata.
