Ok! I've solved this problem too. I've modified the include/port/sco.h in

#ifndef NOFILE
#define NOFILE                  NOFILES_MIN
#endif

#ifndef __GNUC__
#define DISABLE_COMPLEX_MACRO
#endif

#define USE_POSIX_TIME
#define NO_EMPTY_STMTS
#define SYSV_DIRENT

#define HAS_TEST_AND_SET
#define NEED_I386_TAS_ASM

#define USE_UNIVEL_CC

typedef unsigned char slock_t;

/***************************************************************
  * The following include will get the needed prototype for the
  * strcasecmp() function.
  ***************************************************************/
#include <strings.h>

#ifdef __GNUC__
#include <stdarg.h>
#include <netinet/in.h>
#endif

#ifndef                 BIG_ENDIAN
#define                 BIG_ENDIAN              4321
#endif
#ifndef                 LITTLE_ENDIAN
#define                 LITTLE_ENDIAN   1234
#endif
#ifndef                 PDP_ENDIAN
#define                 PDP_ENDIAN              3412
#endif
#ifndef                 BYTE_ORDER
#define                 BYTE_ORDER              LITTLE_ENDIAN
#endif

Postgres compile clean with this. GCC is a very good compiler and generate 
a very fast
code compared with the standard SCO compiler.
If anyone is interested can get it at

http://ww.tekno-soft.it/Files/PostgreSQL-7.0.3/SCO/postgresql-7.0.3-sco5.tgz

it's ~1Mb.

Roberto Fichera.
