This is not going to work. PE style dynamic linking works quite
different from ELF style dynamic linking. Wine can not link native ELF
libraries to windows applications. The .dll.so files from wine are
special in being ELF files but containing extra information that allows
the Wine dynamic linker to link it into PE processes.

This is right. You need at least a correct .spec file to make a wine
dll. You still have to implement a wrapper for each function, as Windows
usually uses the stdcall calling convention, whereas linux uses cdecl by
default. There might be some way to automate writing the wrapper
functions.
