For some reason, when the Windows binary distribution is unzipped with 
Cygwin's unzip, the files are not made executable.

$ unzip darcs-2.2.1-win1.zip

It works if I use Windows' built-in unzip.  This seems to be specific to 
this zip file, if I unzip an older version of darcs I have lying around

$ unzip darcs.zip
Archive:  darcs.zip
   inflating: darcs.exe
$ ls -l darcs.exe
-rwxr-xr-x 1 simonmar mkgroup-l-d 9003999 Aug 20  2008 darcs.exe*

it is executable.

Obviously the workaround is easy: chmod +x *.exe *.dll

but this is just another bump in the road for Windows users, it would be 
nice to squash it.

This zip file is made using 7zip on Windows, that I guess is doing something 
funny.
I'll try using winzip for the next release.
