[mvapich-discuss] Broken multi-threaded support

[Stephan Wolf]

Hi,

the multi-threaded support based on per-object granularity seems to be
broken using gcc47. If I run the following command:
./configure --enable-threads=runtime --enable-thread-cs=per-objec && make -j

I get:
----------------------------

I tried to fix it, but it is too much macro magic for me. Can you have a
look at it?

Thanks
