+{AJ} glibc and gcc might generate some instructions on your machine that
+aren't available on i386.  You've got to tell glibc that you're configuring
+for i386 with adding i386 as your machine, for example:
+
+       ../configure --prefix=/usr i386-pc-linux-gnu
+
+And you need to tell gcc to only generate i386 code, just add `-mcpu=i386'
+(just -m386 doesn't work) to your CFLAGS.
+
+{UD} This applies not only to the i386.  Compiling on a i686 for any older
+model will also fail if the above  methods are not used.
