Please describe a way to repeat the problem. Please try to provide a
concise reproducible example, if at all possible:

Compile the program on a strict ANSI C compiler :-)

If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
The attached patch will fix the problems.

In vacuumc.c, pointer arithmatic was performed on a pointer of type void. The
patch casts the void pointer to a character pointer, does the arithmatic, and
then casts the result back to a void pointer.

In shmem.c, a function of type void returned a value. The patch removes the
offending return statement.
