// Thread local or static memory may be used to reduce the number of (re-)allocations of temporary variables
// in e.g. the ReedSolomonDecoder. It is disabled by default. It can be enabled by modifying the following define.
// Note: The Apple clang compiler until XCode 8 does not support c++11's thread_local.
// The alternative 'static' makes the code thread unsafe.
// for Windows in Visual Studio 2019 on Intel 64-bit using thread_local causes a dependency to VCRUNTIME140_1.dll, so you need 2019 runtime DLLs instead of only 2015 version.

// The Galoir Field abstractions used in Reed-Solomon error correction code can use more memory to eliminate a modulo
// operation. This improves performance but might not be the best option if RAM is scarce. The effect is a few kB big.
