+On x86 GNU/Linux systems the gccgo compiler is able to
+use a small discontiguous stack for goroutines. This permits programs
+to run many more goroutines, since each goroutine can use a relatively
+small stack. Doing this requires using a development version of
+the gold linker. The easiest way to do this is to build
+the GNU binutils, using --enable-gold when you run
+the configure script, and to
+use --with-ld=GOLD_BINARY when you
+configure gccgo. A typical sequence would look like
+this (you can replace /opt/gold with any directory to
+which you have write access):
+
+cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src login +[password is "anoncvs"] +cvs -z 9 -d :pserver:anoncvs@sourceware.org:/cvs/src co binutils +mkdir binutils-objdir +cd binutils-objdir +../src/configure --enable-gold --prefix=/opt/gold +make +make install ++
A number of prerequisites are required to build gcc, as
-described on the gcc web site. If those are all
-available, then a typical build and install sequence would look like
