In MinGW (and as in the defaults in the clang MinGW frontend), the DLL entry point is named `DllMainCRTStartup` which on i386 ends up as `_DllMainCRTStartup at 12`.


Does gcc also pass the entry? If not then we should remove that from clang for consistency.
(Though that is unrelated to your point that --entry should work as it does on ld)
