- REC-01nov91.patches
-
- By Roger Critchlow (rec@arris.com or rec@elf.org).
- ! by Lance Norskog (thinman@netcom.com).
-
- There is one small problem with the Intel 386/SYSV subset of the
- MCC01-01nov91.patches
- to the
- 01nov91.tar.Z
- distribution of Scheme->C. Specifically, most of the garbage collector
- gets excluded by a #ifndef SYSV clause.
-
- The appended patches, which should be applied to scrt/heap.c after the
- MCC01-01nov91.patches, will fix this. Things work much better with the
- garbage collector.
-
- Some other things 386 users should be aware of:
-
- scrt/i386.s should be an empty file. It isn't built by the MCC patches but
- scrt/makefile will look for it.
-
- If you're going to build on a system with 14 character file names, ie most
- System V.3.2 Unix implementations, then you'll need the tar.fix script from
- one of the earlier 386 patch kits, either REC-28sep90.patches or
- SPARC-386.patches.
-
- ! The REC-28sep90.patches file also includes scripts to build shared
- ! library versions of the S2C system and Xlib programs on AT&T V.3
- ! machines. These have not been tested with the 01nov91 release.
-
- ! The use of select() in the read/eval loop causes interaction to
- ! stop working on regular terminals under AT&T Unix V.3. But it
- ! does work under an Xterm window, and on all terminals under
- ! ISC Unix V.3, and probably ESIX, DELL, and SCO as well. You
- ! may have to back off to the 28sep90 read/eval loop for AT&T Unix.
