Well, I assume that you want to produce same export table name for
those functions as they are generated by VC, isn't it? If so, approach
seems to be ok. The issue here is that symbol decoration for stdcall
are different in gcc and VC in export table.
The symbol in import library is as expected (with underscore), but in
export table name entry - ld produces, the underscore lacks. This
isn't really a bug, as it is undefined by MS documentation, and so
nearly every compiler producing different symbol names for stdcall
here. See for this http://www.geocities.com/yongweiwu/stdcall.htm
