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.
