Not good ones.  You could overwrite $(SOURCES), but that may have other
consequences, too.

Well, allow the preprocessor to write its output into a different file.
Even cooler, allow it to read on stdin and output on stdout, unix style.
But anyway let it accept '-o outfile' as argument, and either '-f infile'
(it's ok to let the non-option arguments be input files, too), possibly
with '-' specifying stdin.  At least -o solves the problems with
corrupted sources due to interrupted builds.
