Address trivial build issues on certain Linux distribuitions (e.g. Fedora 20 on which this patch was tested). Most standard C++ libraries had unistd.h removed in GCC 4.7, so add it back in explicitly. Resolve the following ASN.1 build error by specifying the C language tag. libtool: compile: unable to infer tagged configuration libtool: compile: specify a tag with `--tag' Signed-off-by: Tom Tsou <tom@tsou.cc>
