[xml] GetProcAddress and ascii or wide

[Roumen Petrov <bugtrack roumenpetrov info>]

Hi ,

After recent  commits I count not link build for mingw* host  as 
GetProcAddressA is missing.

The "uncode" patch change LoadLibrary to ansi version (LoadLibraryA) and 
MSDN document availability of both versions.

Function GetProcAddress is described as is, i.e. requirements chapter 
lack note for ansi and uncode .


Could we restore GetProcAddress call to old one ?
