I think he needs to add a define of STRICT, the macro which Microsoft
created to be used in all Windows programs to set the expansion of the
header files for work with versions newer than the 16 bit Windows 3.0.  The
macro must be defined before the inclusion of the Windows header files and
is best placed in the IDE's Project|Options|Defines/Conditionals or if using
the command line as -DSTRICT on the compiler command line to the left of the
first file name.

Without the define the Windows header file has an empty list, a (), for the
argument list to the prototype of the EnumWindowsProc argument to
EnumWindows.

This is the same cause as you see causing people to need to cast the WinProc
name when they set the pointer value in a WNDPROC structure prior to calling
RegisterClass.
