Normally this provided path is the last information source which is 
consulted (if all else fails).  Normally the last path component 
(after a "/") would be the name of the program itself.  For example, 
it might be obtained via argv[0].

The sample/test programs do something like this using the argument 
list provided from main():

   InitializeMagick(*argv);

Under Windows, the path used is obtained via NTGetExecutionPath() in 
magick/nt_base.c.  This function uses the GetModuleFileName() sytem 
API.  It likely makes a difference if the program is "static" compiled 
without any additional GM libraries, or if the program uses DLLs.  If 
the program uses DLLs, the reported path is likely the location of the 
DLL since this code would reside in a DLL.
