  What's the right way to do that?  I tried

You specify --large-address-aware if you want it and don't specify if you don't want it.

Sorry, I should have explained more clearly what the issue is. Cygwin's gcc specifies --large-address-aware by default:

$ gcc -dumpspecs | grep large
%{mwindows:--subsystem windows} %{mconsole:--subsystem console} %{!mno-cygwin:%{!mno-use-libstdc-wrappers: --wrap _Znwj --wrap _Znaj --wrap _ZdlPv --wrap _ZdaPv --wrap _ZnwjRKSt9nothrow_t --wrap _ZnajRKSt9nothrow_t --wrap _ZdlPvRKSt9nothrow_t --wrap _ZdaPvRKSt9nothrow_t }} %{shared: %{mdll: %eshared and mdll are not compatible}} %{shared: --shared} %{mdll:--dll} %{static:-Bstatic} %{!static:-Bdynamic} %{shared|mdll: --enable-auto-image-base -e %{mno-cygwin:_DllMainCRTStartup@12} %{!mno-cygwin:__cygwin_dll_entry@12}} %{!mno-cygwin:--dll-search-prefix=cyg %{!shared: %{!mdll: --large-address-aware --tsaware}}}

I'm trying to override this default.
