This is a bug in Xview [1], and the answer to your problem is actually hidden 
on that page:

"If you are using Fedora 8, 9, or 10, or any distribution that includes 
X.org's libX11 version 1.1, you will need to use the i386-FC8 RPMs (or to 
compile XView from the sources included in xview-3.2p1.4-21.1.fc8.src.rpm) to 
avoid XAllocID runtime failures in XView applications."

You will need to recompile the xview library with the latest patches from that 
src rpm applied (or otherwise obtain an updated cygwin binary)
