+       the conventional terminfo layout uses a directory hierarchy with one
+       letter names, while some platforms use two-letter names to work with
+       case-insensitive filesystems.  The configure script searches for a tic
+       program using the AC_CHECK_TOOL macro, which will prefer programs
+       using the canonical host prefix in their name.  You can use this fact
