Yeah, I kind of knew about that. But a type like ssize_t defined with
a typedef won't pass that test. It will degenerate into:
#if defined(OPENSSL_SYS_UEFI) && /*TRUE*/
...
#endif
That brings up the thing I was wondering about. I followed the pattern
in my diffs, but did not feel it was quite right (I might be missing
something obvious)... Why isn't ossl_ssize_t a typedef?
