I simplified the example code that I posted - the actual name I'm
using is much longer. (Sem_R_RTSIM_SHM_READY, R_RTSIM_SHM_READY and
r_rtsim_shm_ready)

I see no warnings or errors during the compile or link. I am linking
the Ada files into a library which is compiled into a C main.

The only thing I do see, is when I add the compile flat to print out
the rep specs - the Semaphore is given two different sizes...

for SEM_R_RTSIM_SHM_READY'Size use 128;
for SEM_R_RTSIM_SHM_READY'Size use 192;

It should be 128, not sure why its later showing as 192... from
looking at the definition for sem_t on this linux system, it should be
128.
