Struct WindowsMsvcRand 

pub struct WindowsMsvcRand { /* private fields */ }

Faithful Windows CRT rand() as used by MSVCRT-family runtimes:

state = state * 214013 + 2531011; return (state >> 16) & 0x7fff;

This is the notoriously weak 15-bit generator associated with many classic Windows/MSVC-era programs. It is included as a bad historical control.
