From 650677461fb95481f02a55f02c356b0d6ce2de52 Mon Sep 17 00:00:00 2001 From: Marcel Raad Date: Fri, 18 Oct 2019 08:19:47 +0200 Subject: examples/sslbackend: fix -Wchar-subscripts warning With the `isdigit` implementation that comes with MSYS2, the argument is used as an array subscript, resulting in a -Wchar-subscripts warning. `isdigit`'s behavior is undefined if the argument is negative and not EOF [0]. As done in lib/curl_ctype.h, cast the `char` variable to `unsigned char` to avoid that.
