lang/gcc47		gcc47-4.7.4.20131130
textproc/ctpp2	ctpp2-2.8.3_1

>Description:
Hi,

in an effort towards upgrading lang/gcc to gcc 4.7, I'm helping gerald@
in making ports gcc47-safe.
Please consider the following patch to your port. If you approve of the
patch, gerald@ has offered his help in commiting it.
If you're commiting yourself or have someone else commit this (or
another patch to the same effect), can you please add an additional
reference to ports/183342 in the commit message?
In my test environment, the port built successfully with lang/gcc47.

>How-To-Repeat:

>Fix:

GCC 4.7 dows not include unistd.h on it's own anymore, so add it
explicitly.

# add unistd.h
$ svn status
