[PATCH] compile fails with gcc-4.7 on Fedora Core 17

[Christian Beer]

When compiling on Fedora Core 17 with gcc-4.7 the make fails at several places with something like:

error: 'unlink' was not declared in this scope
error: 'chdir' was not declared in this scope
error: 'getpid' was not declared in this scope

This can be fixed by adding

#include <unistd.h>

to the files:

tools/process_input_template.cpp
tools/create_work.cpp
sched/single_job_assimilator.cpp
vda/vda.cpp
vda/vdad.cpp
