Compile may fail for sh_unix.c

[rainer]

Compiling of sh_unix.c may fail. because dependencies cause the preprocessor to pick up linux/wait.h, which contains #define statements for symbols that are typedef'ed in sys/wait.h:

typedef enum
{
P_ALL, /* Wait for any child. */
P_PID, /* Wait for specified process. */
P_PGID /* Wait for members of process group. */
} idtype_t;

will fail if P_ALL etc. are defined as numerical constants already; need to #undef them.

Fixed in changeset [169].
