Problem(s) diagnosed:

1. awk.exe is just a cygwin symlink for me, and since I'm not running
   emacs under cygwin... boom!

2. quoting for awk needs to use double quotes, not single quotes for
   some reason

3. CMD doesn't cope, no way, no how, with newlines in the command line
   (at least, not in any way I've found)

Recipe for a fix in my environment, in Man-filter-list:

a. replace "awk" with "gawk"
b. remove all newlines from the gawk arguments
c. backslash-escape existing double quotes in the gawk arguments
d. replace single quotes in the gawk arguments with double quotes

(setq Man-filter-list (quote (("sed" "" "-e '/^[-][-]*$/d'" "-e 
'/[789]/s///g'" "-e '/Reformatting page.  Wait/d'" "-e '/Reformatting entry.  
Wait/d'" "-e '/^[    ]*Hewlett-Packard[      ]Company[       ]*-[    ][0-9]*[
