+    # static linking works just fine, just do not use it for libc (or other
+    # libraries that make system calls). ncurses use -static only for linking
+    # the curses library, then switches back to -dynamic - so they should be fine.
+    # FIXME: for target, we only need tic (terminfo compiler). However, building
+    # it also builds ncurses anyway, and dedicated targets (install.includes and
+    # install.progs) do not do well with parallel make (-jX).
