The former is somewhat misnamed. 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.
