Nope.  It actually seems to be due to a change in automake.  Apparently, 
make distcheck did not previously 'chmod -R a-w'.  At least, that's how 
I interpret Alexandre Duret-Lutz's email on the automake list:

"This test" being the "remove all write perms and pretend we're on a 
CDROM".  (Sure, 'make distcheck' existed in 1.4, but not with the a-w 
thing).

So, when you were using automake with squid, you still had write perms 
on the files and thus 'cp -p' worked without problems.

Hypothesis: if you built and installed automake-1.4l, and then tried to 
re-autotool your squid source tree, it would fail make distcheck even if 
you use the same cygwin1.dll that you were using 3-4 months ago.
