I already found a source: http://www.bigbiz.com/cgi-bin/listman?2 which 
contains ascii formatted man pages for Linux.  I used curl(1) to 
download the man pages, converted back to man(1) format, and installed 
them.  I'm sure there are other pages besides the syscall version.  At 
least I have a more current copy.  My old version is at least 10 years 
old. Before B20 of Cygwin.

Is Linux open-source??  Is is legal/possible to use these applicable pages?
