^^^^^^^^^^^^ Emutls still exists on Linux: $ objdump -T /usr/lib/x86_64-linux-gnu/libgcc_s.so.1 | grep -F emutls 0000000000019700 g DF .text 0000000000000184 GCC_4.3.0 __emutls_get_address 0000000000019890 g DF .text 0000000000000035 GCC_4.3.0 __emutls_register_common On Linux I suspect threading is built into libc.so, so there is no explicitly dependency on libpthread.so.
I wonder how much of all of this is necessary for building an SEH only exception handler.
SEH doesn't require TLS (but SJLJ does). If dependency on winpthread is undesired, you may build the win32 thread model.
