- ultimately caused the server to print multiple copies
- when it was busy (STR #1184)
- - The cupsFile API now uses the O_APPEND option when
- opening files in append mode (STR #990)

- private and have been renamed to avoid conflicts with
- other implementations with the same name.

- fonts (STR #1093)
