Hi,
I've resolved this problem modifying the file
/gcc-i386-rtems/i386-rtems/include/sys/dirent.h before start RTEMS
building procedure. I think this file is owned by newlib... :

    char		d_name[NAME_MAX + 1];	/* before */

          modified to fix a compiling error with :

    char		d_name[14 + 1];         /* after */

Good Work !
