--- Comment #9 from Brecht Sanders <brechtsanders at users dot sourceforge.net> ---
Any update on this?
Issue still exists today (in GCC 11.2.0 and in latest snapshot
11.2.1-20210814).

Both when building gcc on Windows for nvptx as well as the offload engine for
nvptx there is an error like this in nvptx-none/libatomic/config.log:

configure:3736: $? = 1
configure:3756: checking whether the C compiler works
