8 * On Linux up to 2.4.21 sendfile() (syscall #187) works with 32-bit
9 * offsets only and the including <sys/sendfile.h> breaks building
10 * if off_t is 64 bit wide. So we use own sendfile() definition where
11 * offset paramter is int32_t. It allows to use sendfile() with
12 * the file parts below 2G.
13 *
14 * Linux 2.4.21 has a new sendfile64() syscall #239.
