+@item --enable-altivec
+Specify that the target supports AltiVec vector enhancements. This
+option will adjust the ABI for AltiVec enhancements, as well as generate
+AltiVec code when appropriate. This option is only available for
+PowerPC systems.
+
@item --enable-target-optspace
Specify that target
libraries should be optimized for code space instead of code speed.
