## Test creating a DLL and linking against the DLL without using an import
|
|
## library.
|
|
|
|
## Test on i386 with cdecl decorated symbols.
|
|
|
|
## Linking the executable with -opt:noref, to make sure that we don't
|
|
## pull in more import entries than what's needed, even if not running GC.
