samba - Nov 2004 - Compile error with 3.0.8

We are compiling samba on AIX 5.1 with

export CC=gcc
export CPPFLAGS="-I/usr/local/include -I/usr/local/ssl/lib/include"
export LDFLAGS="-L/usr/local/lib -L/usr/local/ssl/lib"
./configure --enable-shared=no --enable-static=yes"

we get the following error when using make:

Compiling libsmb/clifile.c
libsmb/clifile.c: In function `cli_unix_stat`
libsmb/clifile.c:216: error `STAT_ST_BLOCKSIZE' undeclared ....

Can someone help
