FIND_SOURCE_FILES is *not* a list of source files---it is a procedure to list source files to its standard output. FIND_C_SOUCRES sounds as if it is a similar procedure, which would be implemented much like FIND_C_SOURCES = $(FIND_SOURCE_FILES) | sed -n -e '/\.c$/p' but that is not what you did and that is not what you want to have. Perhaps call it FOUND_C_SOURCES? I wonder if we can get rid of FIND_SOURCE_FILES that is a mere procedure and replace its use with a true list of source files. Would it make the result more pleasant to work with? Perhaps something like the attached patch, (which would come before this entire thing as a clean-up, and removing the need for 2/3)? I dunno. Using a procedure whose output is fed to xargs has an advantage that a platform with very short command line limit can still work with many source files, but the way you create and use COCCI_SOURCES in this patch would defeat that advantage anyway, so perhaps we can get away with an approach like this. Having a list of things in $(MAKE) variable has a longer-term benefit that we could exploit more parallelism if we wanted to, too.
