+*** Dumping error when using GNU binutils / GNU ld on a Sun.
+
+Errors similar to the following:
+
+ Dumping under the name xemacs unexec():
+ dldump(/space/rpluim/xemacs-obj/src/xemacs): ld.so.1: ./temacs:
+ fatal: /space/rpluim/xemacs-obj/src/xemacs: unknown dynamic entry:
+ 1879048176
+
+are caused by using GNU ld. There are several workarounds available:
+
+In XEmacs 21.2 or later, configure using the new portable dumper
+(--pdump).
+
+Alternatively, you can link using the Sun version of ld, which is
+normally held in /usr/ccs/bin. This can be done by one of:
+
+- building gcc with these configure flags:
+ configure --with-ld=/usr/ccs/bin/ld --with-as=/usr/ccs/bin/as
+
+- adding -B/usr/ccs/bin/ to CFLAGS used to configure XEmacs
+ (Note: The trailing '/' there is significant.)
+
+- uninstalling GNU ld.
+
+The Solaris2 FAQ claims:
+
+ When you install gcc, don't make the mistake of installing
+ GNU binutils or GNU libc, they are not as capable as their
+ counterparts you get with Solaris 2.x.
