For what its worth, 3.1 libsupc++.a and libstdc++.a build natively with mingw. (libsupc++.a contains the eh and new/delete stuff that is currently in libgcc.a for mingw). Locale class support is missing (as it is with cygwin/newlib), but C-locale works for me. Wide char support is missing, because of deficiencies in C-runtime. If you want wide char with -mno-cygwin, you'll need an auxiliary library -- like mingw's [incomplete] libisocext.a -- to supply C wide char support. Iostreams work for <char>. In 3.1 -mno-cygwin needs the mingw32/bits headers. Also, there may be differences in the way the C_runtime functions are promoted into namespace std. As far as size, linking in libstdc++.a has a big cost. Some of that will be reduced by getting rid of the extensive tree checking that is currently on by default. Also, the -ffunction-sections, -fdata-sections (now on by default in libstdc++.a builds) don't really seem to add any value, but I haven't played with them yet..
