Depending on the windows target version (_WIN32_WINNT), the used SDK and the build configuration the linker will see multiple libraries exporting the same symbols. To prevent ugly hacks (e.g. modifying cmake's default system libraries or fragile library linking order chains) we prefix these functions with "winpr_" and create corresponding defines to keep the current api names.
