That doesn't compile:

In file included from ../math/math.h:472:0,
                 from ../include/math.h:3,
                 from test-signgam-finite-c99.c:24:
../sysdeps/m68k/m680x0/fpu/bits/mathinline.h:153:1: error: â__leaf__â attribute has no effect on unit local functions [-Werror=attributes]
 __inline_mathop(__atan, atan)
