What is/are the limits of the unsigned integer in the BCF format with regards to the POSITION (POS) field, which in the specification it is described as a:
BCF2 site information encoding Field Type l_shared uint32_t
Data length from CHROM to the end of INFO l_indiv uint32_t
Does it depend on being compiled for 64bit or 32bit architectures?

In C a uint32_t is always a 4 bytes-unsigned-integer whatever the architecture is.
So its' capacity goes from 0 to 2^32 =4,294,967,296

Well, 1-4,294,967,296 if we're talking about printed positions or 0-4,294,967,295 as stored in the file (the range is [0, 2^32-1]).
