Update zopfli to Mar 10, 2013 Google state
Support zopfli in single thread case
Add -F, -I, -M, and -O options for zopfli tuning
- 2.3.2 xx Jan 2015 -
+ 2.3.2 24 Jan 2015 Change whereis to which in Makefile for portability
+ Return zero exit code when only warnings are issued
+ Increase speed of unlzw (Unix compress decompression)
+ Update zopfli to current google state
+ Allow larger maximum blocksize (-b), now 512 MiB
+ Do not require that -d precede -N, -n, -T options
+ Strip any path from header name for -dN or -dNT
+ Remove use of PATH_MAX (PATH_MAX is not reliable)
+ Do not abort on inflate data error, do remaining files
+ Check gzip header CRC if present
+ Improve decompression error detection and reporting
