* kmp_wrapper_getpid.h -- getpid() declaration.

// On Unix-like systems (Linux* OS and OS X*) getpid() is declared in standard headers.
#include <sys/types.h>
#include <unistd.h>
// On Windows* OS _getpid() returns int (not pid_t) and is declared in "process.h".
#include <process.h>
// Let us simulate Unix.
typedef int pid_t;
#define getpid _getpid
#error Unknown or unsupported OS.
TODO: All the libomp source code uses pid_t type for storing the result of getpid(), it is good.
But often it printed as "%d", that is not good, because it ignores pid_t definition (may pid_t
be longer that int?). It seems all pid prints should be rewritten as
printf( "%" KMP_UINT64_SPEC, (kmp_uint64) pid );
or (at least) as
printf( "%" KMP_UINT32_SPEC, (kmp_uint32) pid );
(kmp_uint32, kmp_uint64, KMP_UINT64_SPEC, and KMP_UNIT32_SPEC are defined in "kmp_os.h".)
