+# In order to work around the very problems that force us to now generally
+# create a libgcc.so, glibc reexported a number of routines from libgcc.a.
+# By now choosing the same version tags for these specific routines, we
+# maintain enough binary compatibility to allow future versions of glibc
+# to defer implementation of these routines to libgcc.so via DT_AUXILIARY.
