The changes required for glibc was:
1) removing the -export-symbols-regex "^g.*" passed to libtool
2) adding -Wl,-version-script=libglib-2.0.ver to libglib_2_0_la_LDFLAGS
3) creating the .ver file

A sample file (marking just one symbol as GLIB_2_24 for demonstration
purposes) looks like that:

Are you talking about glibc or glib? It's a bit confusing to me...

Looks like glib to me, not much glibc around ;-)
