+      * load both of those libraries from the same directory based
+      * on the theory that co-located libraries are compatible.

-      * We have to make sure we use the two files from the same directory
-      * in case there are more than one copy on the system because
-      * one version of dbgeng.dll might not be compatible with a

-      * env. var. DEBUGGINGTOOLSFORWINDOWS, next in the default
-      * installation dir for DTFW, and lastly in the standard
-      * system directory.  We expect that that we will find
-      * them in the standard system directory on all systems
-      * newer than Windows 2000.
+      * On Windows 2000 and earlier, dbgeng.dll and dbghelp.dll were
+      * not included as part of the standard system directory. On
+      * systems newer than Windows 2000, dbgeng.dll and dbghelp.dll
+      * are included in the standard system directory. However, the
+      * versions included in the standard system directory may not
+      * be able to handle symbol information for the newer compilers.
+      *
+      * We search for and explicitly load the libraries using the
+      * following directory search order:
+      *
+      * - java.home/bin (same as $JAVA_HOME/jre/bin)
+      * - dir named by DEBUGGINGTOOLSFORWINDOWS environment variable
+      * - various "Debugging Tools For Windows" program directories
+      * - the system directory ($SYSROOT/system32)
+      *
+      * If SA is invoked with -Dsun.jvm.hotspot.loadLibrary.DEBUG=1,
+      * then debug messages about library loading are printed to
