Even for a header that's not defined in any standard, as an installed
header you should avoid names in the user's namespace that are not
explicitly part of the API for the user to use. That is, unless you
actually intend the name arc_fpu_getcw to be a supported interface for
users including <fpu_control.h>, you should name it __arc_fpu_getcw, and
you should use __cw to avoid conflicting with any user macro called sw.
(Function definitions also need to be in GNU style - function name at the
start of a line, space before '('.)
