src/backend/commands/copy.c revision 1.176 needs <errno.h>

Hi,

When compiling from current sources obtained via cvsup the build
failed in src/backend/commands/copy.c (revision 1.176) as errno is
used but <errno.h> is not included. Trivial diff below.

$ uname -srm
NetBSD 1.5.1 i386
$ gcc -v
Using builtin specs.
gcc version egcs-2.91.66 19990314 (egcs-1.1.2 release)

Regards,

Giles
