-// reasons:
-// - VC6 version of imagehlp.h doesn't define it
-// - VC7 one does
-// - testing for compiler version doesn't work as you can install and use
-// the new SDK headers with VC6
-//
-// in any case, the user may override by defining wxUSE_DBGHELP himself
+// All known versions of imagehlp.h define API_VERSION_NUMBER but it's not
+// documented, so deal with the possibility that it's not defined just in case.
