Previously, c.h made <assert.h> only available in frontends (#ifdef FRONTEND), which was probably reasonable, because the only thing it would give you is assert(), which you generally shouldn't use in the backend. But with C11, <assert.h> also makes available static_assert(), which would be useful everywhere. So this patch moves <assert.h> to the commonly available header files in c.h and fixes a small complication in regcustom.h that resulted from that.
