Why /usr/bin/*.dll must be executable?

So, I had to play with "chmod -x cyg*.dll" and, of course, it 
totally hosed Cygwin. I recovered by reinstalling from scratch 
only after realizing that ATTRIB did not have an option to re-
establish X--we're talking XP here.  So, as this is a Windows 
thing, wondering how, through Windows, I could restore execute 
access to the DLLs.
