Maybe because neither _has_ POSIX pread? This is cygwin's pread, I believe:

http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/cygwin/fhandler_disk_file.cc?rev=1.225...

Windows has means to implement it natively, but the interface is so ugly
(see OVERLAPPED, if interested), that it is no wonder Cygwin chose to
just use lseek.
