There is no concrete definition of -ffast-math and users will have
different expectations.  Numerical programs for astrodynamics may
expect precisions even for -ffast-math and OTOH there are many
programs which don't take care of precisions at all and prefer
sin&cos instead of sinf&cosf.  I guess that the former doesn't make
much sense for SH4A in the first place and for users of the latter
with -ffast-math, the proposed change may be a bit surprising.
I have no strong opinion for this, though.  I also won't object to
the suggested patch.
