?S:d_statfs:
?S:	This variable conditionally defines the HAS_STATFS symbol, which
?S:	indicates to the C program that the statfs() routine is available.
?S:.
?S:d_statfs_s:
?S:	This variable conditionally defines the HAS_STRUCT_STATFS symbol,
?S:	which indicates that the struct statfs is supported.
?S:.
?S:d_fs_data_s:
?S:	This variable conditionally defines the HAS_STRUCT_FS_DATA symbol,
?S:	which indicates that the struct fs_data is supported.
?S:.
?S:d_statfs_f_flags:
?S:	This variable conditionally defines the HAS_STRUCT_STATFS_F_FLAGS
?S:	symbol, which indicates to struct statfs from has f_flags member.
?S:	This kind of struct statfs is coming from sys/mount.h (BSD),
?S:	not from sys/statfs.h (SYSV).
?S:.
?C:HAS_STATFS:
?C:	This symbol, if defined, indicates that the statfs routine is
?C:	available to stat filesystems by filenames.
?C:.
?C:HAS_STRUCT_STATFS:
?C:	This symbol, if defined, indicates that the struct statfs
?C:	to do statfs() is supported.
?C:.
?C:HAS_STRUCT_FS_DATA:
?C:	This symbol, if defined, indicates that the struct fs_data
?C:	to do statfs() is supported.
?C:.
?C:HAS_STRUCT_STATFS_F_FLAGS:
?C:	This symbol, if defined, indicates that the struct statfs
?C:	does have the f_flags member containing the mount flags of
?C:	the filesystem containing the file.
?C:	This kind of struct statfs is coming from <sys/mount.h> (BSD 4.3),
?C:	not from <sys/statfs.h> (SYSV).  Older BSDs (like Ultrix) do not
?C:	have statfs() and struct statfs, they have ustat() and statfs()
?C:	with struct fs_data.
