Comment:

 It was a mistake to default tcl to --enable-corefoundation as
 CoreFoundation is incompatible with code using fork() without immediately
 calling exec().[[BR]]

 Since both --enable-threads and --enable-corefoundation are incompatible
 with fork(), it makes much more[[BR]]
 sense to just move --enable-corefoundation into the threads variant
 instead.
