-*** Digital Unix 4.0: Garbled display on non-X terminals when Emacs runs.
-
-So far it appears that running `tset' triggers this problem (when TERM
-is vt100, at least). If you do not run `tset', then Emacs displays
-properly. If someone can tell us precisely which effect of running
-`tset' actually causes the problem, we may be able to implement a fix
-in Emacs.
-
-*** SVr4
-
-**** SVr4: On some variants of SVR4, Emacs does not work at all with X.
-
-Try defining BROKEN_FIONREAD in your config.h file. If this solves
-the problem, please send a bug report to tell us this is needed; be
-sure to say exactly what type of machine and system you are using.
-
-**** SVr4: After running emacs once, subsequent invocations crash.
-
-Some versions of SVR4 have a serious bug in the implementation of the
-mmap () system call in the kernel; this causes emacs to run correctly
-the first time, and then crash when run a second time.
-
-Contact your vendor and ask for the mmap bug fix; in the mean time,
-you may be able to work around the problem by adding a line to your
-operating system description file (whose name is reported by the
-configure script) that reads:
-#define SYSTEM_MALLOC
-This makes Emacs use memory less efficiently, but seems to work around
-the kernel bug.
-
-*** SCO Unix and UnixWare
-
-**** SCO 4.2.0: Regular expressions matching bugs on SCO systems.
-
-On SCO, there are problems in regexp matching when Emacs is compiled
-with the system compiler. The compiler version is "Microsoft C
-version 6", SCO 4.2.0h Dev Sys Maintenance Supplement 01/06/93; Quick
-C Compiler Version 1.00.46 (Beta). The solution is to compile with
-GCC.
-
-**** UnixWare 2.1: Error 12 (virtual memory exceeded) when dumping Emacs.
