- /*
- * uname() emulation by Dave Gymer. In the public domain.
- * Bugs:
- * The MiNT version stuff is in the release field. According to the GNU
- * shell utils this is the way SunOS does it, so we put the TOS
- * version number in the 'version' field (even under MiNT).
- *
- * (Modified slightly by ERS.)
