*** Note: ***
|
|
There is currently one importants side effect when doing static linking.
|
|
|
|
If you include a function statically than its required to be present
|
|
in the supplied DLLs of your OS and Hardware.
|
|
This means if the DLL is not present your program will not run.
|
|
In Win95 it appears that you will be informined you about
|
|
the name of the first missing symbol while loading the executable.
