[Yaffs] Compile error when using yaffs/direct

When i try to compile yaffs/direct I get strange errrors. I am running the
original Makefile in yaffs/direct on Linux.

Some of the errors:

[gustad@tuxsrv1 work]$ make
gcc -c -Wall -DCONFIG_YAFFS_DIRECT -DCONFIG_YAFFS_SHORT_NAMES_IN_RAM -g
dtest.c -o dtest.o
In file included from yaffscfg.h:12,
                 from yaffsfs.h:10,
                 from dtest.c:9:

yaffs_guts.h:355: parse error before '.' token
yaffs_guts.h:372: parse error before '}' token

This rows plus some more concerning the same variables is the problem.

    __u32 st_atime;  /*  time of last access */
    __u32 st_mtime;  /*  time of last modification */
    __u32 st_ctime;   /*  time of last change */

Can somebody help me?
