8 months ago - OS variable was unused
- ifndef section is not needed since "make PREFIX=... MANPREFIX=..." overwrites whatever is set there
- notdir is a GNU specific function (not POSIX) and doesn't do anything in this case
- "sed -i" is not POSIX and pointless if pipes are used correctly
- the "if" block can be removed since "sed" can also be used to copy files to the destination.
