The discussion so far has been based on the idea that the user is expressing
an order on the command line and will be surprised if that order is not
followed. That definitely makes sense, and I was quite shocked to discover
this problem. ("make -j clean all" does /what/?!)
But when I ran into this

Parsing the file specification myself wasn't a good idea. I sho

That's effectively what MinGW does anyway, (although it does it through

Yes, that's what the Gnulib utimecmp module does: the idea is that after
every stat-like operation you look at the file's time stamps to infer
more information about the containing file

All calls to memory allocation in GNU make should use the x*() functions
(xmalloc, xcalloc, xrealloc, xstrdup) which will stop the process if
memory allocation fails.
