close() function is not declared properly on HP-UX when using death tests

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile any test case using death test asserts (eq. EXPECT_EXIT()) on 
HP-UX

What is the expected output? What do you see instead?

The following error occurs:

gtest-1.3.0/include/gtest/internal/gtest-death-test-internal.h", line 209: 
error #2020: 
          identifier "close" is undefined
        close(status_fd_);

What version of the product are you using? On what operating system?

gtest 1.3.0

uname -a
HP-UX B.11.31 U ia64 0383467329 unlimited-user license

aCC -V
aCC: HP C/aC++ B3910B A.06.22 [Nov 14 2008]

Please provide any additional information below.

The <unistd.h> should be included explicitly. The patch below solves this 
problem:

I think this is fixed in 1.5.0?

Seems to be. Unfortunately I cannot re-test it on HP-UX at the moment.
