Hi All,

I had failures with building libcap-2.25 with the new gperf. From the 
fail messages I can see that the libcap build calls gperf and is finding 
unknown type names in the response.

I have seen that Matthias has updated libcap and submitted the patch.

I will wait till the updated libcap is merged and then redo my gperf 
build and see if that solves the problem. Until then I have excluded 
gperf from my current builds.

Here is the log output from building libcap with gperf updated from 
3.0.4 (2009) to 3.1 (2017).
