"zstd -vvv" prints wrong file size

[dearblue]

Describe the bug

The size of a huge file is printed incorrectly with zstd -vvv.

To Reproduce

% truncate -s4g zero.bin

% /usr/local/bin/zstd -fvvv zero.bin
*** zstd command line interface 64-bits v1.4.8, by Yann Collet ***
set nb workers = 1
zero.bin: 0 bytes
zero.bin             :  0.00%   (4294967296 => 134676 bytes, zero.bin.zst)
zero.bin             : Completed in 4.30 sec  (cpu load : 100%)

Expected behavior

Expected:

zero.bin: 4294967296 bytes

Desktop (please complete the following information):

• OS: FreeBSD 12.2-RELEASE-p4 GENERIC
• Version: 1.4.8

Additional context

The reason is that it is truncated to lower 32-bit in DISPLAYLEVEL().

zstd/programs/fileio.c

Line 1512 in 5158071

DISPLAYLEVEL(5, "%s: %u bytes \n", srcFileName, (unsigned)fileSize);

This can be solved by changing the display to show the value as 64-bit.
