I did think that you understood how to use CVS to research things like
this, but, ok, so there was some historical ignoramus who worked on the
cygwin project and didn't understand how symlinks worked.

You made assumptions with your "it sould probably be better" suggestion.
The point is that it isn't usually profitable to automatically assume
that a problem would be trivially solved by an obvious solution.

Your reading of the Makefile is not right. libc.a and libm.a from
newlib do get used in creating cygwin1.dll (obviously?). There are
different libc.a, libm.a, libpthread.a, libutil.a, libdl.a, and
libresolv.a libraries which are all produced intentionally and have
nothing to do with the creation of the dll itself.
The initial discussion of the reason for these libraries started here:
