The difference is that you can statically link GTK+, and it'll work. You can't statically link glibc, if you want to be able to resolve hostnames or users, because of NSS modules.

Static linking itself doesn't prevent modules. There's https://github.com/pikhq/musl-nscd for example

		Not inherently, but static linking to glibc will not get you there without substantial additional effort, and static linking to a non-glibc C library will by default get you an absence of NSS.
