/* The use_jemalloc_allocations function is called from the memory management
initialization routines in the mysys and innobase libraries when building with
MSVC on Windows to decide whether to use jemalloc or std::malloc for memory
allocations.

Returning true from this function means that those libraries will use jemalloc.

Returning false from this function means that those libraries will use
std::malloc.

If the MSVC linker cannot find a function definition with this name, it will
fall back to using an alternate name (that is defined within the mysys and
innobase libraries to return false.)
