* fhandler_disk_file.cc (fhandler_base::fstat_helper): Always check executable suffix to get x-bits for .exe files also in notexec case. Always reopen file when checking for file header. * ntdll.h (wait_pending): Delete. * path.cc (symlink_info::check_shortcut): Drop call to wait_pending since file is always opened for sync IO. (symlink_info::check_sysfile): Ditto. (MIN_STAT_ACCESS): Remove. (FULL_STAT_ACCESS): Remove. (symlink_info::check): Drop access flag. Revert to open file with just read attributes access. Reorder symlink check to check for reparse points first. Don't check reparse points for anything else, even on remote drives. Open file for GENERIC_READ when trying to read shortcuts or system-bit symlinks. Accommodate dropped access flag in call to path_conv_handle::set. * path.h (class path_conv_handle): Drop access flag and accommodate all related methods.
