[lmi] trivial patch for LoadLibrary() call

[Vadim Zeitlin]

 Hello,

 Could you please apply this trivial patch?

 #ifdef LMI_MSW
     fenv_initialize();

-    if(0 == ::LoadLibrary(dll_name.c_str()))
+    if(0 == ::LoadLibraryA(dll_name.c_str()))
         {
         std::ostringstream oss;
         oss << "Failed to preload '" << dll_name << "'.";

The reason for it is that LoadLibrary() is #define'd as LoadLibraryW() in
Unicode build by <windows.h> while dll_name is always std::string (and not
a std::wstring) and so there is mismatch in parameter types if wx is built
in Unicode, as it is by default in the trunk.

This (and a few other changes which I'll describe in separate messages...)
would allow me to build LMI using wx svn trunk again.

 Thanks,
VZ
