I don't see anything in the config script that checks for gcc - you might take a look at it to check. It's in config/orte_check_tm.m4 on our developer's trunk

We assume that we can link lib torque into a C application (if this is a problem for you, it's a huge deal breaker for us, since OMPI is a C library).  What does config.log say when checking for tm_init?

Brian,

libtorque can still be linked in to C applications. In testing with a simple C program, we did have to add 

void *__gxx_personality_v0;

to the C program. Here is the error reported by the configure script:

Oddly enough, if you have already configured with an older version of TORQUE, you can build open-mpi with TORQUE 4.2 installed, so it can find the function definitions when compiling, its just for some reason it doesn't find them in the configure script. This is why I think that something in the configure script is assuming that libtorque was compiled with gcc.
