dnl pkg-config versioning
dnl
dnl Once we released gluster-api.pc in 3.5 with version=6. Since then we undid
dnl the library versioning and replaced it with symbol-versioning. The current
dnl libgfapi.so has version 0, but the symbols have the version from the main
dnl package at the time they were added.
dnl
dnl Because other packages (like samba) use the pkg-config version, we can not
dnl drop it, or decrease the version easily. The simplest solution is to keep
dnl the version=6 and add sub-digits for the actual package/symbol versions.
