No, not at all unfortunately. Doing this doesn't get you around your
initial stated concern, which is a valid one, of linking MSVCRT. You'll
either need to remove the dependency in the library code itself or forgo
using the library. There's a slim chance you'd get lucky and squeak by
with both MSVCRT and cygwin1.dll in the same code but if you don't know
what you're doing, the likelihood of success for this is minimal. I
can't recommend it.

I guess, in a nutshell, you're starting from a faulty premise as I
explained above. The rest of what you see is just fallout from that
first mistep.
Sorry I don't have better news for you.
