Hi Enrique,
I don't immediately see what the problem may be. I installed the cygwin-doc 
package with the 64-bit Cygwin setup.exe on Windows 7 and it all went well. 
More below...

To see the mkshortcut source, you can use setup.exe to install the latest 
cygutils package and click the box saying you want source too.  It will go into 
/usr/src. cd into the newly-created cygutils* directory there and do 'cygport 
prep' to prepare the source tree for all of cygutils (it's not much).  Then 
navigate down to the mkshortcut directory and see mkshortcut.c.

Or use gitweb to inspect the source online. The cygutils source tree is at
git://cygwin.com/cygwin-apps/cygutils.git . You can reach it from the cygwin.com 
home page -- click on "Source in Git" on the left side of the page.

How do you enable native symbolic links?  And also, could you please provide the 
output of 'cygcheck -svr' as an email attachment on your next reply? Please make 
sure to attach, and not just append it to the email, as the latter tends to 
poison searches of the archives.
Thanks,

..mark
