Hi!

Android is hopeless, its C library (bionic) is a very trimmed down and bug 
ridden version of the BSD library. The Android devel team is not willing to 
fix any bugs unless they affect native Android applications or Dalvik.

In particular the .so loader and related initialization is broken. dlopen() 
doesn't properly call initializers, dlclose() doesn't work at all.

Unless a proper C library is installed on the target systems (and a matching 
cross-toolchain used for compiling) there are no chances wine will run on 
Android. Many of the libraries required for Wine will not work properly with 
bionic even if they may compile.
