	    An audit was performed on libcap and friends by https://x41-dsec.de/
             https://x41-dsec.de/news/2023/05/15/libcap-source-code-audit/
             The audit (final report, 2023-05-10)
              https://drive.google.com/file/d/1lsuC_tQbQ5pCE2Sy_skw0a7hTzQyQh2C/view?usp=sharing
              was sponsored by the the Open Source Technology Improvement Fund,
              https://ostif.org/ (blog). Five issues were found. Four of them are
              addressed in this release. Each issue was labeled in the audit results as
              follows:
	        LCAP-CR-23-01 (SEVERITY) LOW (CVE-2023-2602) - found by David Gstir
	        LCAP-CR-23-02 (SEVERITY) MEDIUM (CVE-2023-2603) - found by Richard Weinberger
	        LCAP-CR-23-100 (SEVERITY) NONE
	        LCAP-CR-23-101 (SEVERITY) NONE
	    Man page style improvement from Emanuele Torre
	    Partially revive the ability to build the binaries fully statically.
	        This was needed to make bleeding edge kernel debugging/testing via
                 qemu+busybox work again. Addressing an issue I realized only when I
                 tried to answer this stackexchange question.
