installed in the shared library, and then relink Emacs.
If you have already installed the name resolver in the file libresolv.a,
-then you need to compile Emacs to use that library. The easiest way to
-do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE
-or LIB_STANDARD which uses -lresolv. Watch out! If you redefine a macro
-that is already in use in your configuration to supply some other libraries,
-be careful not to lose the others.
-
-Thus, you could start by adding this to config.h:
-
-#define LIBS_SYSTEM -lresolv
-
-Then if this gives you an error for redefining a macro, and you see that
-config.h already defines LIBS_SYSTEM as -lfoo -lbar at some other point
-(possibly in an included file) you could change it to say this:
-
-#define LIBS_SYSTEM -lresolv -lfoo -lbar
+then you need to compile Emacs to use that library.

This problem seems to be a matter of configuring the DECserver to use
7 bit characters rather than 8 bit characters.

-* Build problems on legacy systems
-
-** SunOS: Emacs gets error message from linker on Sun.
-
-If the error message says that a symbol such as `f68881_used' or
-`ffpa_used' or `start_float' is undefined, this probably indicates
-that you have compiled some libraries, such as the X libraries,
-with a floating point option other than the default.
-
-It's not terribly hard to make this work with small changes in
-crt0.c together with linking with Fcrt1.o, Wcrt1.o or Mcrt1.o.
-However, the easiest approach is to build Xlib with the default
-floating point option: -fsoft.
-
-** HPUX 10.20: Emacs crashes during dumping on the HPPA machine.
-
-This seems to be due to a GCC bug; it is fixed in GCC 2.8.1.
-
-** Vax C compiler bugs affecting Emacs.
-
-You may get one of these problems compiling Emacs:
-
- foo.c line nnn: compiler error: no table entry for op STASG
- foo.c: fatal error in /lib/ccom
-
-These are due to bugs in the C compiler; the code is valid C.
-Unfortunately, the bugs are unpredictable: the same construct
-may compile properly or trigger one of these bugs, depending
-on what else is in the source file being compiled. Even changes
-in header files that should not affect the file being compiled
-can affect whether the bug happens. In addition, sometimes files
-that compile correctly on one machine get this bug on another machine.
-
-As a result, it is hard for me to make sure this bug will not affect
-you. I have attempted to find and alter these constructs, but more
-can always appear. However, I can tell you how to deal with it if it
-should happen. The bug comes from having an indexed reference to an
-array of Lisp_Objects, as an argument in a function call:
- Lisp_Object *args;
- ...
- ... foo (5, args[i], ...)...
-putting the argument into a temporary variable first, as in
- Lisp_Object *args;
- Lisp_Object tem;
- ...
- tem = args[i];
- ... foo (r, tem, ...)...
-causes the problem to go away.
-The `contents' field of a Lisp vector is an array of Lisp_Objects,
-so you may see the problem happening with indexed references to that.
