Hello!

I try to configure source3 from last samba4 tarball on Debian Etch AMD64 and get an error:
checking if large file support can be enabled... checking for 64 bit off_t... no
configure: error: "large file support support not available: sizeof(off_t) != 8"

But early I see:
checking size of off_t... 8

I try to compile test myself:
cat test.c 
#include <stdio.h>
#include <sys/stat.h>
main() { exit((sizeof(off_t) == 8) ? 0 : 1); }
gcc test.c
test.c: In function 'main':
test.c:3: warning: incompatible implicit declaration of built-in function 'exit'
test.c:3: error: 'off_t' undeclared (first use in this function)
test.c:3: error: (Each undeclared identifier is reported only once
test.c:3: error: for each function it appears in.)

After adding "#include <sys/types.h>"
Test compiled and run ok
