# REQUIRES: x86
## Test creating a DLL and linking against the DLL without using an import
## library.
## Test on i386 with stdcall/fastcall/vectorcall decorated symbols.
## Check that we normally warn about these fixups. If -stdcall-fixup:no
## (--disable-stdcall-fixup on the MinGW linker level) is passed, we don't
## do these fixups. If we -stdcall-fixup (--enable-stdcall-fixup on the MinGW
## linker level) is passed, we don't warn about it at all.
