web server compiling errors

Hi, I’ve used the CORTEX_LM3Sxxxx_IAR_Keil demo to one of my project. Everything seems OK, until I got the compiling errors regarding in httpd-fsdata.c file. I copied as below for your analysis.  I’ve checked the head file that defines the struct httpd_fsdata_file{}. It is included. I wonder if some one knows what wrong is. This is uIP web server demo. webserverhttpd-fsdata.c(456): error:  #70: incomplete type is not allowed
webserverhttpd-fsdata.c(456): error:  #20: identifier “NULL” is undefined
webserverhttpd-fsdata.c(458): error:  #70: incomplete type is not allowed
webserverhttpd-fsdata.c(460): error:  #70: incomplete type is not allowed
webserverhttpd-fsdata.c(462): error:  #70: incomplete type is not allowed
webserverhttpd-fsdata.c(464): error:  #70: incomplete type is not allowed
webserverhttpd-fsdata.c(466): error:  #70: incomplete type is not allowed Thanks,
