Problem when compiling avifile

I have a problem when trying to install avifile.

I have this problem in the instalation process (when run make):

 -fomit-frame-pointer -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 
-D_GNU_SOURCE -pipe -c flvenc.c  -fPIC -DPIC -o flvenc.lo
flvenc.c: In function `flv_write_trailer':
flvenc.c:232: parse error before `file_size'
flvenc.c:234: `flags' undeclared (first use in this function)
flvenc.c:234: (Each undeclared identifier is reported only once
flvenc.c:234: for each function it appears in.)
flvenc.c:238: `file_size' undeclared (first use in this function)
make[2]: *** [flvenc.lo] Error 1
make[2]: Saliendo directorio 
`/stuff/files/store/Apps_TARBALL/transcode/avifile-0.7-0.7.38/ffmpeg/libavformat'

make[1]: Saliendo directorio 
`/stuff/files/store/Apps_TARBALL/transcode/avifile-0.7-0.7.38/ffmpeg'
make: *** [all-recursive] Error 1

I have Red Hat 7.3, and i have the library ffmpeg, divx and other 
necessary.......

Do you know what's the matter?

THANKS!
