why apr_arch_utf8.h does not use extern "C" to export symbols for C++ user

[troy]

Hi all,

There are some header files not in include/arch folder,  say 
include\arch\win32\apr_arch_utf8.h.  The symbols “apr_conv_utf8_to_ucs2” and 
“apr_conv_ucs2_to_utf8” are not embraced with extern “C”.

It gives me trouble to locate the symbols. Is it a bug? 

Troy Represents Oh Yeah   ✌
