Indeed. I tried building against 1.3.6 (mainly because it was laying
around) and the error reported by Devrim is just the tip of the iceberg.
With "make -k", I see unknown-symbol failures on
ZSTD_CCtx_setParameter
ZSTD_c_compressionLevel
ZSTD_c_nbWorkers
ZSTD_CCtx_reset
ZSTD_reset_session_only
ZSTD_compressStream2
ZSTD_e_continue
ZSTD_e_end
I wonder whether Robert's ambition to be compatible with old versions
extends that far.
