RFA; configuring GCC --disable-libgomp causes libstdc++ abi check to fail.

[Iain Sandoe]

Hello,

I was running some checks on x86_64-linux-gnu (most recently r191461), and configured GCC with --disable-libgomp.

This causes FAIL: libstdc++-abi/abi_check for both default and m32.

The failure is in 11 missing symbols (listed at the end of this post), from two objects which are no longer built:
libstdc++-v3/src/compatibility-parallel_list.o, libstdc++-v3/src/c++98/parallel_settings.o.

Is this intended?
I.E. that the libstdc++ ABI depends on the presence of libgomp?

thanks,
Iain
