We'd still spawn a utility each > time we compile a unit. 'true' is internal shell function, so only shell is called. If full path=20 will be specified as /usr/bin/true, make calls it directly without shell. /usr/bin/true is much smaller but still one process will be created. Another variant is to create suffix rule for all such cases (using some=20 intermediate pseudo-suffix) and specify .if defined() there only once. --=20 http://ache.pp.ru/ --gKMricLos+KVdGMg Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkhampwACgkQVg5YK5ZEdN2jdwCfXLHuH0Z0xuJr9qn81hNoFqSi rpAAn0bQyPmw6I8v5+HR7aNWDoEY48od =Q4El -----END PGP SIGNATURE----- --gKMricLos+KVdGMg--
