This change is for building phodav on OSX/Darwin
I am able to build and run spice-webdavd on Catalina/Xcode using brew for meson, glib etc.
- meson defaults to clang and it builds with a warning. Clang spice-webdav runs but there are more warnings with G_MESSAGES_DEBUG=all. After a few file/folder operations my Spice client (Fedora 34, remote-viewer 9.0) crashed
- Using CC=gcc-11 (homebrew) for meson builds without warnings.
gcc spice-webdav logs fewer warnings at runtime and also works better. I can copy files, extract archives etc. It seems more robust than the clang build but I got a timeout trying to clone a repository into the webdav folder.
