Dear maintainer, the homepage https://sourceforge.net/projects/posixovl that is currently mentionned in the fuse-posixovl package metadata points to https://inai.de/projects/posixovl/
There, we can see that the current version is actually 1.4. Also, commit f5d992133b seems to fix the build issue (i did not try but it renames strlcpy with px_strlcpy), and is part of 1.4 release. So, i guess that changing upstream homepage URL to https://inai.de/projects/posixovl/ and updgrade to 1.4. will fix this issue. Ciao, Thierry
