[Kaz Kojima <kkojima at rr dot iij4u dot or dot jp>]

Hi,

I've committed the attached patch to fix the build failure
for sh3-unknown-linux-gnu:

../sysdeps/ieee754/dbl-64/e_exp.c: In function '__ieee754_exp':
../sysdeps/ieee754/dbl-64/e_exp.c:61:3: error: 'FE_TONEAREST' undeclared (first use in this function)

Regards,
	kaz
