That's a fair question. They may work, as they are also exposed / available via the standalone R math library (see Writing R Extensions). As such, they may not required memory allocations or other interactions with the R process and hence "not call R ... in any fashion" per the above. But we can't say for sure. If you want to be safe, maybe stick to equivalent functions from a non-R source: C++11, Boost, ...
