From 709fdce0893f93464435841e0eb9f6df3fd73807 Mon Sep 17 00:00:00 2001 From: Patrick Steinhardt Date: Fri, 6 Dec 2024 11:27:18 +0100 Subject: [PATCH] compat/win32: fix -Wsign-compare warning in "wWinMain()" GCC generates a warning in "headless.c" because we compare `slash` with `size`, where the former is an `int` and the latter is a `size_t`. Fix the warning by storing `slash` as a `size_t`, as well. This commit is being singled out because the file does not include the "git-compat-util.h" header, and consequently, we cannot easily mark it with the `DISABLE_SIGN_COMPARE_WARNING` macro.
