It's very simple, dmake keeps a state file (if asked).  In this case, 
the contents are:

.MAKE_VERSION:	VERSION-1.0
.BUILT_LAST_MAKE_RUN:
x.o:	a/x.h /lib/libc.so /lib/libm.so /opt/studio/lib/libCrun.so 
/opt/studio/lib/libCstd.so
	CC x.cc -o x -I b -I a

So it knows a/x.h was used in the last build and it knows the compiler 
options and libraries used.
