 The fix is to install an unshared library that corresponds to what you

 If you have already installed the name resolver in the file libresolv.a,

 do this is to add to config.h a definition of LIBS_SYSTEM, LIBS_MACHINE

-
-**** SunOS: You get linker errors
-   ld: Undefined symbol
-      _get_wmShellWidgetClass
-      _get_applicationShellWidgetClass
-
-**** Sun 4.0.x: M-x shell persistently reports "Process shell exited abnormally with code 1".
-
-This happened on Suns as a result of what is said to be a bug in Sunos
-version 4.0.x.  The only fix was to reboot the machine.
-
-**** SunOS4.1.1 and SunOS4.1.3: Mail is lost when sent to local aliases.
-
-Many emacs mail user agents (VM and rmail, for instance) use the
-sendmail.el library.  This library can arrange for mail to be
-delivered by passing messages to the /usr/lib/sendmail (usually)
-program .  In doing so, it passes the '-t' flag to sendmail, which
-means that the name of the recipient of the message is not on the
-command line and, therefore, that sendmail must parse the message to
-obtain the destination address.
-
-There is a bug in the SunOS4.1.1 and SunOS4.1.3 versions of sendmail.
-In short, when given the -t flag, the SunOS sendmail won't recognize
-non-local (i.e. NIS) aliases.  It has been reported that the Solaris
-2.x versions of sendmail do not have this bug.  For those using SunOS
-4.1, the best fix is to install sendmail V8 or IDA sendmail (which
-have other advantages over the regular sendmail as well).  At the time
-of this writing, these official versions are available:
-
- Sendmail V8 on ftp.cs.berkeley.edu in /ucb/sendmail:
-   sendmail.8.6.9.base.tar.Z (the base system source & documentation)
-   sendmail.8.6.9.cf.tar.Z   (configuration files)
-   sendmail.8.6.9.misc.tar.Z (miscellaneous support programs)
-   sendmail.8.6.9.xdoc.tar.Z (extended documentation, with postscript)
-
- IDA sendmail on vixen.cso.uiuc.edu in /pub:
-   sendmail-5.67b+IDA-1.5.tar.gz
-
-**** Sunos 4: You get the error ld: Undefined symbol __lib_version.
-
-This is the result of using cc or gcc with the shared library meant
-for acc (the Sunpro compiler).  Check your LD_LIBRARY_PATH and delete
-/usr/lang/SC2.0.1 or some similar directory.
-
-**** SunOS 4.1.3: Emacs unpredictably crashes in _yp_dobind_soft.
-
-This happens if you configure Emacs specifying just `sparc-sun-sunos4'
-on a system that is version 4.1.3.  You must specify the precise
-version number (or let configure figure out the configuration, which
-it can do perfectly well for SunOS).
-
-**** Sunos 4.1.3: Emacs gets hung shortly after startup.
