No, they have different calling conventions, so they'd just not exist.

One of the gains from dropping the non-reentrant ones comes from
eliminating static arrays. In current uClibc, these static arrays are
eliminated by the use of uc_malloc, which has the drawback that all of
these functions can suddenly call exit, contrary to their documentation.
I'd like to get that reverted.

It would be better if the caller provided the buffers, so that they
don't have to exist in uClibc. It's the better interface.
