I would hope that ghc will link to editline-ext on all platforms.
That gives ghc the functionality it needs without getting
into legal trouble with the license. Then those who want the full
readline interface can install readline-ext, and those who
want the full editline interface can install editline.
GHC is in no legal trouble whatsoever... only if proprietary Haskell
code uses the readline library and doesn't switch to using the editline
backend. On Linux here I have readline installed and not editline
currently, so it seems silly to require installing editline by default
("default" meaning "if I don't want to, I have to figure out the right
configure flag to give to allow readline to be used"). It makes sense
to use editline by default for Mac and Windows builds though, where
readline isn't native, I guess. Statically linking to editline for
binary builds would be alright (not exporting any readline to
ghc-compiled programs by default?). How is "Search for editline first;
if not found, try to use readline"?
