Comment (by barracuda156):

 Replying to [comment:3 kencu]:
 > Looking at the portfile, I cannot see how this should be building with
 gcc13 on 10.6 i386 anyway.

 BTW, judging from this, it will not build with Clang on certain Intel cpus
 either: https://stackoverflow.com/questions/22395292/assembler-messages-
 no-such-instruction-xbegin
 Since TSX is not necessarily supported on hardware level:
 https://en.wikipedia.org/wiki/Transactional_Synchronization_Extensions

 After disabling `__TBB_TSX_INTRINSICS_PRESENT` I have `OneTBB` built.
