# 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.
