This paragraph is now misleading.  All of the gcc/ directory (except maybe
parts of config/) uses ISO C function definitions - the files can hardly
any longer be considered to be written to be usable with K&R compilers,
but there will still be embedded K&R assumptions (other than function
definition style, e.g. lack of string concatentation and excess casts)
that should freely be converted to ISO C. While libiberty may have its own
requirements.
