Yes, it overwrite the rest.  Most of the flags are warning flags (-W*), 
and it doesn't matter if you have them in.

You find the list either in the console output of configure ("C++ compiler 
flags are" or some thing like that), or you can look into the 
Alps/config.log file - at the end is a list of all variables that 
configure has determined, and you can find CXXFLAGS there.  You can do a 
configure run without setting CXXFLAGS on the command line, get the 
default out of the config.log file, and then copy it, removing 
-mno-cygwin.
