The pg_basebackup code has WalSegSz as uint32, whereas the rest of the 
code has it as int.  This seems confusing, and using the extra range 
wouldn't actually work.  This was in the original commit (fc49e24fa6), 
but I suppose it was an oversight.

Subject: [PATCH] pg_basebackup: Correct type of WalSegSz

The pg_basebackup code had WalSegSz as uint32, whereas the rest of the
code has it as int.  This seems confusing, and using the extra range
wouldn't actually work.
