Actually, the conditionals leading to 'PLUGIN_NVPTX_DYNAMIC=1' here do
control two orthogonal aspects; OK to disentangle that with the attached
"libgomp nvptx plugin: Split 'PLUGIN_NVPTX_DYNAMIC' into
'PLUGIN_NVPTX_INCLUDE_SYSTEM_CUDA_H' and 'PLUGIN_NVPTX_LINK_LIBCUDA'"?
Hi Thomas,
we discussed dropping --with-cuda, so do I understand it correctly that
you now propose to drop --with-cuda and --with-cuda-driver-lib but
intend to keep --with-cuda-driver-include ?
Can you explain what user or maintainer scenario is served by this? Is
there a problem with using gcc's cuda.h?
Thanks,
- Tom

Thomas
