[Bug-tar] maybe bug?

[Kostich, Mitchell]

I have tried tar-1.29 and tar-1.27.1 (from https://ftp.gnu.org/gnu/tar/) with 
same 'make check' error popping up all over the test suite. This error ends up 
percolating into other programs that use tar also. 

I've commented comments w/ '##', and output with '#'.

The error is:
# value 771780898 out of uid_t range 0..2097151

I thought UIDs should be in the range [0..(2^21 - 1)]? Why test with 771780898? 
Is this a negative int getting expressed as unsigned?

The build commands are:
./configure --prefix=$HOME/opt/tar
make -j 10
## so far so good
make check
## many failed tests follow, all with same message. I understand that this may 
not be a critical error, but it makes the testing output almost useless, as 
there are so many failures it is hard to find anything that might actually 
matter. 
##   furthermore, the errors percolate into other tool builds, like automake, 
which generates hundreds of errors during 'make check', all of the ones which 
I've checked repeating this same basic uid_t error.

I've attached one of the error test log files (002 -- the first place the error 
shows up), along with the overall test summary.

some system info:

## BTW, I tried very recent gcc version too with no success (same error). I've 
also tried ./configure --prefix=$HOME/opt/tar DEFAULT_ARCHIVE_FORMAT=POSIX
## I also tried setting flags --without-posix-acls and --without-xattrs without 
resolving the issue.

Not sure what other info you may need. I'm new to bug reporting.

Many thanks for your time,
