Here is the list for the things I renamed, including for dwarf.h :

/usr/local/include/atf-c/defs.h /usr/local/include/iconv.h =

It looks like iconv.h is from something later removed but was not =
cleaned out at the time. I have /usr/local/include/readline/ material =
from the same time frame:

but "pkg which" reports those files as being from readline-6.3.8 .
I guess I can just delete would would normally have been =
/usr/local/include/iconv.h .
