Samuel Neves a4ce789f28 fix some compiler warnings 2022-01-08 18:00:52 -05:00
TheVice 58926046ca [MSVC] added possible to compile at Microsoft Visual C compiler. 
[main.c] removed including of unistd.h from c/main.c file.
[blake3_avx2.c|blake3_avx512.c|blake3_sse41.c] resolved compile error:
'C4146' - applying of unary minus operator to the unsigned value.
