Ticket #4522 (closed bug: fixed)
.ghc folder not created by default
|Reported by:||guest||Owned by:||igloo|
|Type of failure:||None/Unknown||Difficulty:|

This may have been fixed in later versions -- but using the generic 6.12.3 binary (still recommended for use with the platform) I didn't have a command line history across sessions.
I created a ~/.ghc folder by hand, and then the ghci_history file was created there and everything worked fine.
