MSinfrastructure... If we were to support multiple libraries, would they be selected at run time or compile
time? If only compile time, how would it work for the Windows installer with the SChannel thingy --- would they have
to distribute two separate packages, for OpenSSL and SChannel?
While I have successfully performed runtime conditional dynamic
loading inside programs (each shared library with its own list of
dependent libraries) on one platform with one selected dynamic loading
API, I cannot say I recommend it. This would aid neither portability,
debug-ability, or performance (though compared to the overhead of SSL,
the jump table is kinda irrelevant).
