The build of gperf-3.1 went without any problems with libcap-2.49

The only think I found was that there was a message "Changes in libcap-2.49 check rootfile!" and there were a lot of lines with +usr/share/gocode/src/kernel.org/pub/linux/libs/security/libcap.....


A patch for the update of gperf will be submitted shortly.

Adolf.
