The 1st argument is the VAR I want to dump the results into.  That's not 
the problem.  Assume that EXCESSIVE_CPPFLAGS_LIST contains a whole bunch 
of junk separated with semicolons.  Getting rid of the semicolons is the 
problem.

I wrote a totally separate script and proved that
STRING(REPLACE ";" " " EXCESSIVE_CPPFLAGS "${EXCESSIVE_CPPFLAGS_LIST}")
is supposed to work.  Now, is it me or is it CMake...
