Permission handling for the other OS -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Permission handling for the other OS From: K Thananchayan <thananck@yahoo.com> Preserve exec permission under Windows on existing source files. Not an ideal solution as there is no way to specify exec permission for a new file. Nevertheless, this helps working on crossplatform projects. manifest hash: c50da52ad4645f40bd6204c4fd458e880bc3f801 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCuvJeywK+sNU5EO8RAscXAJ40eAHZjTip5to6BGPdoXxxL5gNQQCgl5GT 8S1Ckank5I/0ScGtapZKqTA= =QrQp -----END PGP SIGNATURE-----
