I nailed, it's another problem with the export keyword.


stdcall.d:
---
export extern (Windows) void (*funcptr)(int);

void main()
{
    funcptr(5);
}
---

Just to show how funcptr gets mangled:

c:\prog\test\D>dmd stdcall
c:\prog\dmd\bin\..\..\dm\bin\link.exe stdcall,,,user32+kernel32/noi;
OPTLINK (R) for Win32  Release 7.50B1

c:\prog\dmd\bin\..\lib\phobos.lib(dmain2)
 Error 42: Symbol Undefined _funcptr at 0
--- errorlevel 1


funcptr is mangled as _funcptr at 0, which I believe is a stdcall function of zero
arguments.  This is clearly wrong, and won't link with the corresponding C
definition of the function pointer.
