Right now, I really don't know. Hmm. Except, maybe, since you seem to be set up to build Cygwin from CVS, could you start building the 09-12 version from CVS and then just add one change from CVS at a time using cvs up -D 'yyyy-mm-dd HH:MM' as filter until you encounter the problem? An interesting situation to test would be, if you have the state after this change: 2010-09-12 Corinna Vinschen <...> * sec_acl.cc (acl_worker): Remove. (acl32): Implement acl_worker functionality here. (lacl32): Just return -1 with errno set to ENOSYS. (lacl): Ditto. * include/cygwin/acl.h (lacl): Remove this call. and then just add this single change from the first 2010-09-13 checkin: * fhandler_tty.cc (fhandler_tty_slave::init): Use tty::setpgid method. Then, finally, add the entire 2010-09-13 checkin. At which point exactly does Cygwin keel over?
