Feel free to invent any other __*_VISIBLE tag to exclude this addition=20 =66rom namespace for programs which may define their own SEEK_DATA etc=20 which is allowed f.e. in POSIX namespace. Look like other __*_VISIBLE tags= =20 are implemented and what they does. Default is turn all on. In any case adding them to stdio.h is premature action - I not see yet corresponding fseek() code. --=20 http://ache.pp.ru/ --J2SCkAp4GZ/dPZZf Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.3 (FreeBSD) iD8DBQFGFkb/Vg5YK5ZEdN0RAmsEAJ9lwWP8RjRfqrgmtrWHQJmgvT6xKQCgqInC NBrexJjV5KcOXF6PHeb2mmM= =CHDV -----END PGP SIGNATURE----- --J2SCkAp4GZ/dPZZf--
