45 This file turns a regular Windows PE image into a DLL. Because of
46 the complexity of this operation, it has been broken down into a
47 number of separate modules which are all called by the main function
48 at the end of this file. This function is not re-entrant and is
49 normally only called once, so static variables are used to reduce
50 the number of parameters and return values required.
