+Subject: [PATCH] giscanner: remove dependency on distutils.msvccompiler
+
+It was removed with setuptools 74.0.0. Since we still depend on the
+MSVCCompiler class use new_compiler() to get it some other way.
+
+Remove any reference to MSVC9Compiler, which was for Visual Studio 2008
+which we no longer support anyway.
+
+Fixes #515
