Those should be fixed separately, in a patch that fixes the affected 
functions for all of float, double and long double rather than letting the 
float versions diverge from the double and long double versions.  To keep 
down divergence, the versions fixed should include 
sysdeps/ieee754/ldbl-128ibm/{s_ctanhl.c,s_ctanl.c} as well.
