+# Detemine whether we need to use the -no-undefined linker flag
+# when building shared libraries.  
+# Sets NO_UNDEFINED to "" or "-no-undefined"
+# 
+# As far as I can tell, we need -no-undefined only when building
+# windows DLLs.  This occurs when using MinGW and Cygwin.
+#
+# For now, we stub this out.
