You know I spoke too soon.  Once I changed that, I started getting 
semicolons in new places *inside of* quoted strings.  There is a general 
problem of semicolons, double quotes, and spaces in filenames beating 
each other up, as they are passed around between lists and strings and 
replacements are performed.  A list of defines like the following is 
highly problematic:

 -DHIERARCHICAL_INSTALL -DC_USE_C_DEFAULTS -DC_INSTALL_HOME="E:/Program 
Files/Chicken" -DC_INSTALL_BIN_HOME="E:/Program Files/Chicken/bin" 
-DC_INSTALL_INCLUDE_HOME="E:/Program Files/Chicken/include" 
-DC_INSTALL_LIB_HOME="E:/Program Files/Chicken/lib" -DHAVE_DIRECT_H 
-DHAVE_GCVT -DHAVE_STDINT_H -DHAVE_WINDOWS_H -DHAVE_LOADLIBRARY 
-DHAVE_GETPROCADDRESS -DHAVE_WINSOCK2_H -DHAVE_WS2TCPIP_H 
-DC_ENABLE_PTABLES -DC_STACK_GROWS_DOWNWARD=1

I'll try to ask a specific question when I've got it back down to a 
specific problem again.  Until then, any general remedies?
