I make a first pass of converting this makefile into an nmake makefile.
As you can see, it doesn't look to hard to do this conversion.
Note, that nmake will generate the -I and -D options based on
.SOURCE.h and on variables with ==. Moreover, it scans source files looking
both includes and variables whose names match the == names and generates
the subset that is needed. If the value of any of these change,
only modules that use the specific variable get recompiled.
There is no need to list headers since this will be found automatically.
