2283,WIndows: loading objects that refer to DLL symbols,simonmar,,"This is a test case from #1288, distilled into a separate report so I can close #1288:

`test3b.c`:
{{{
#include <stdio.h>

__declspec(dllexport) void _stdcall test(int arg)
{
   printf(""The argument passed was %i\n"", arg );
}
}}}

`test_proxy_5a.c`:
{{{
__declspec(dllimport) void _stdcall test(int arg);

void test_proxy(int arg)
{
   test(arg);
}
}}}

To reproduce:
{{{
gcc -c test3b.c
ar -rv test3b.a test3b.o 
c:/mingw/bin/dllwrap --export-all-symbols --output-lib test3b.dll.a -o test3b.dll test3b.a
gcc -c test_proxy_5a.c
ghci -ltest3b test_proxy_5a.o
}}}

the error message we get:

{{{
GHCi, version 6.9.20080512: http://www.haskell.org/ghc/  :? for help

ghc.exe:
test_proxy_5a.o: unknown symbol `__imp__test'

}}}

I'm not sure to what extent we need to support this, it's possible to link to the DLL by omitting the dllimport declaration.
