Clement Courbet b3c9fc27b4 Optimized loop bounds to allow the compiler to unroll the loop. 
This has no measurable impact on large files but improves small file
decompression by ~1-2% for 10kB, benchmarked with:

head -c 10000 silesia.tar > /tmp/test
make CC=/usr/local/bin/clang-9 BUILD_STATIC=1 && ./lzbench -ezstd -t1,5 /tmp/test

John Ericson 0ede342acc Fix MinGW cross build from Unix 
generate_res.bat seems rather pointless, am I missing something? I just
inlined it into the Makefile.

Ryan Schmidt 6ddb783c3e Change c90 to c89 
c89 and c90 are the same language. Old compilers like gcc 4.2.1 don't
know the c90 alias.

W. Felix Handte c13f81905a Fix #1861: Restrict overlapLog Parameter When Not Built With Multithreading 
This parameter is unused in single-threaded compression. We should make it
behave like the other multithread-only parameters, for which we only accept
zero when we are not built with multithreading.

Yann Collet 31a0abbfda updated pzstd and largeNbDicts to use the new FileNamesTable* abstraction 2019-11-06 09:10:05 -08:00
Björn Ketelaars e488cabf25 'date -r FILE' is non-portable. 
date(1) is used to display the last modification time of a file, which
is not supported on OpenBSD, FreeBSD and Darwin. Instead use stat(1).

Tested on OpenBSD.

Björn Ketelaars 66b6688274 'head -c BYTES' is non-portable. 
Similar to #1321: The '-c' option for 'head' is non-portable (not in
POSIX).
