- How do system administrators and users manage multiple incompatible Fortran compilers on their systems? How can `g77` contribute to this, or at least avoiding intefering with it? Currently, `g77` provides rudimentary ways to choose whether to overwrite portions of other Fortran compilation systems (such as the `f77` command and the `libf2c` library). Is this sufficient? What happens when users choose not to overwrite these--does `g77` work properly in all such installations, picking up its own versions, or does it pick up the existing "alien" versions it didn't overwrite with its own, possibly leading to subtle bugs?
- `LOC()` and other intrinsics are probably somewhat misclassified. Is the a need for more precise classification of intrinsics, and if so, what are the appropriate groupings? Is there a need to individually enable/disable/delete/hide intrinsics from the command line?
