+This EXE links to and dynamically loads seven DLLs, t_nestdll1-7.dll.
+The diagram below shows the structure of the linkage. Regular arrows
+are normal static linkage, arrows marked with DY are dynamic loads with
+RLibrary::Load.
+
+ +-----+ +---+ +---+
+ | EXE |----->| 1 |--DY->| 3 |
+ +-----+ +---+ +---+\
+ | \ \ EXE and 3 both link to 2
+ D \ \ +---+
+ Y +------------------------+-->| 2 |
+ | +---+
+ v
+ +---+
+ | 5 |

+ D \
+ Y \

+ v \

+ | 6 | \

+ | \
+ D \
+ Y \
+ | \
+ v \ 5 and 7 both link to 4
+ +---+ \ +---+
+ | 7 |---------------+-->| 4 |
+ +---+ +---+
+
+The result should be that the constructors are called in order from 1 to 7,
+with no constructor being called more than once or omitted.
