building xfsprogs (CVS): fadvise.c:71: `POSIX_FADV_NORMAL' undeclared (first use in this function)

[Bernhard Erdmann <be@xxxxxxxxxxx>]

Hi,

I'm trying to build the current version of xfsprogs (2.6.24) on a RHL 
6.2 box. "make" fails. xfsprogs 2.6.19 or 2.6.21 (don't know anymore) 
was compiled cleanly.
gcc -O1 -g -DDEBUG -funsigned-char -fno-strict-aliasing -Wall 
-DVERSION=\"2.6.24\" -DLOCALEDIR=\"/usr/share/locale\" 
-DPACKAGE=\"xfsprogs\" -I../include -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 
-DHAVE_FADVISE -DHAVE_MINCORE -DHAVE_INJECT -DHAVE_RESBLKS 
-DHAVE_SHUTDOWN   -c -o fadvise.o fadvise.c
