Cannot build with gcc 4.7.0

[zcbenz]

Got this error when compiling:

In file included from seccompsandbox/library.cc:7:0:
seccompsandbox/library.h:159:46: error: ‘ssize_t’ has not been declared
make: *** [out/Debug/obj.target/seccomp_sandbox/seccompsandbox/library.o] Error 1
make: *** Waiting for unfinished jobs....

This bug was caused by not including unistd.h, which was not revealed by compiler until gcc 4.7.

Upstream chromium also had bugs of this type, see http://code.google.com/p/chromium/issues/detail?id=120724&can=1&q=GCC%204.7&colspec=ID%20Pri%20Mstone%20ReleaseBlock%20Area%20Feature%20Status%20Owner%20Summary

As I saw in the official chromium repository, most of these bugs were fixed in the upstream, should rogerwang /chromium be synced to a near version?
