 So, the package doesn't do anything particularly offensive here; it
 tries running cpp as follows:
 
    $CPP "$CPPFLAGS" foo.c > foo.o
    $CPP -traditional-cpp -E foo.c > foo.o
    $CPP -E foo.c > foo.o
    $CPP -traditional-cpp -pipe foo.c > foo.o
    $CPP -pipe foo.c > foo.o
 
 It does not seem to me that any of these invocations should make the
 cwrappers wrapper belch if the old wrapper didn't belch either. So I
 suppose the question is: which of these fail, and why? Examining
 work.log should reveal at least which one's different.
 
 To figure out why it might be necessary to use make build-env and run
 the wrapper cpp by hand...
 
 
 (If the package is specifically trying to get a traditional cpp it
 should probably be using tradcpp instead, though.)
