5.7.4 Adding a MYICON.ICO Line to the Makefile

In the makefile, add the MYICON.ICO file to the list of files on which ICON.RES is dependent. The relevant lines in the makefile should look like this:

icon.res: icon.rc icon.h myicon.ico
     rc /r icon.rc

This change ensures that, if the MYICON.ICO file changes, ICON.RC will be recompiled to form a new ICON.RES file.

No other changes are required.
