◆ SEQAN3_WORKAROUND_GCC_NO_CXX11_ABI

#define SEQAN3_WORKAROUND_GCC_NO_CXX11_ABI 0

This is needed to support CentOS 7 or RHEL 7; Newer CentOS's include a more modern default-gcc version making this macro obsolete.

In GCC 5 there was a bigger ABI change and modern systems compile with dual ABI, but some enterprise systems (those where gcc 4 is the standard compiler) don't support dual ABI. This has the effect that even community builds of gcc are build with –disable-libstdcxx-dual-abi. Only building the compiler yourself would solve this problem.
