No, [w/o a makefile] it does the get and compile, then removes the
g-file and object file, but it recognizes that the built executable is
up-to-date.

nmake (modified SCCS.mk to avoid the redirection issue) does not;
'nmake a.c' exhibits pathological behavior; nmake does the get then
immediately removes the target!

Following is captured results with gmake and nmake on a simple program
and also showing the pathological behavior noted above:
