+Subject: [PATCH] glib_stubs: avoid GLib g_free macro redefinition error
+
+glib 2.78+ defines g_free as an object-size checking macro.
+open-vm-tools overrides g_free(), leading to preprocessor expansion
+inside the function signature and breaking the build.
+
+Undefine the macro before defining the stub.
+
+Upstream-Status: Submitted [https://github.com/vmware/open-vm-tools/pull/779]
