b1e707f772 - Corrected issue 31 : LZ4 correctly accepts compressing data when the output buffer has exactly the required size (it was a bit over-cautious in previous version). 
- Added : a fuzzer tool
Thanks to Andrew Mahone, for contribution on both points

cfbace25d7 lz4.c : changed a tuning parameter name to MEMORY_USAGE, to better reflect its impact 
Makefile : default produces native binary, all produce native & 32-bits binaries

d9ef5117f6 Changed Makefile default setting to generate only native binary. 
The 32-bits version can still be generated (on 64-bits systems) using :
make lz4demo32
