Any reasonably recent version of the glibc should do, but:
- you may be using the glibc from your toolchain, so changing glibc may
mean changing toolchain;
- well, the glibc is a bit the heart of the user-space support. It has
more than one files. And changing them may change a lot of things.

So, I think, the simpler thing for you is to use xenomai shared memories.
