putting this in the exported header is problematic. as you see with the libctf
code, anyone including bfd.h now has to make sure string.h is included first
even if they don't use the header themselves. this is generally considered bad
form for headers.
along those lines, a bunch of sim ports are broken now as they include bfd.h
but not all happen to include string.h first.
