If you look at the readline recipe, you see this

--8<---------------cut here---------------start------------->8---
                   ,@(if (target-mingw?)
                         ;; MinGW: termcap in ncurses
                         ;; some SIG_* #defined in _POSIX
                         '(#:make-flags '("TERMCAP_LIB=-lncurses"
                                          "CPPFLAGS=-D_POSIX -D'chown(f,o,g)=0'"))
                         '())
--8<---------------cut here---------------end--------------->8---

I would consider this pretty ugly.  I think we tried and decided to
temporarily (ahem) use this option because adding the patch would
trigger a world rebuild for all archs.  I think we meant to remove the
above code and insert the patch when merging core-updates or something?
