sounds stupid to say thanks to @myself, I simply based entire PR on some other diff that added another codec

All those functions ( pmalloc(), pfree(), CharWriter, CharWriterFunc() ) should be moved to lzbench_ppmd_compress(). They are small enough to move to the function body. Compressors.cpp is not private yard, it's public space and you should not litter it.

@tansy sorry for late reply. PR updated.

FYI, when I tried to use latest LZMA SDK 23.01 (instead of 22.01) I got compilation errors because lzbench already contains older lzma sdk parts (specifically 7zTypes.h, Compiler.h, Precomp.h and others are conflicting). With 22.01 at least it compiles cleanly.

when lzma is updated to 23.01, libppmd should also be updated to 23.01 at the same time

FYI @inikep
