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 AT 12} 
%{!mno-cygwin:__cygwin_dll_entry AT 12}} 
%{!mno-cygwin:--dll-search-prefix=cyg     %{!shared: %{!mdll: 
--large-address-aware --tsaware}}}

I'm trying to override this default.

Ken
