- I was wondering what that meant. The new mintlib readme metions
- -mpcrel (or something). What does this mean; under what conditions will
- gcc generate non-pc-relative code? Does the new gcc support both shared
- and private data in the same program?
- I would also like to bother you about tcsh. I have version 6.00.02,
- and it doesn't complete dir names. Is 6.02.00 available? Also, would it
- be fairly simple to support threading and other options through shell_p?
- And finally, how come tcsh needs such a huge stack?
