For the life of me I can't figure out which variable is supposedly undefined:

requestRegion(); });
Nevertheless, this has never led to a crash as far as I know; so,
probably a bogus warning indeed.
None of the other code (except for the SHARED libraries, but they
are already anyway) need to be compiled with -fPIC. That flags
can therefore now be removed from fs-build-variables.
I have no idea if I can use <FS:Ale> (it isn't used elsewhere right now).
If the FS tags are meant only for those with write access to the
repository then I guess it should be changed into <FS:Beq>.
path is treated as a null-terminated string, which is only guaranteed
when the buffer that strncpy copies to is at least one larger than
the maximum number of characters copied (the third argument).
Without this patch, g++ 13.2.1 gives a warning turned into an error.
