FYI,

this little script which I call cgcc is useful for checking projects that
does seem compile right when $CC fails to create .o files.  It runs first
the checker and then the compiler.  It's in perl for no particular good
reason.

You could even run in this mode normally if you don't mind that your
compiles take extra time.  Just do

    make CC=/scratch/welinder/sparse/cgcc

or something like that.

#!/usr/bin/perl -w
# -----------------------------------------------------------------------------

my $cc = $ENV{'REAL_CC'} || 'cc';
my $check = $ENV{'CHECK'} || 'check';

# Look for a .c file.  We don't want to the checker on .o or .so files
# in the link run.  (This simplistic check knows nothing about options
# with arguments, but it seems to do the job.)
my $seen_a_c_file = 0;
foreach (@ARGV) {
    if (/^[^-].*\.c/) {
	$seen_a_c_file = 1;
	last;
    }
}

if ($seen_a_c_file) {
    system ($check, @ARGV);
}

exec ($cc, @ARGV);
