Re: Combined tree builds for mingw32

The failing command is trying to compile the PCH. This means that
we're including a large number of libstdc++ headers in a row. One of
the first ones pulls in c++config.h, which has #undef max; but so far,
nothing has included <windows.h>. Later, something includes
gthr-default.h; on this platform that pulls in <windows.h>, which
eventually #define's min. Then later we get <limits>, which now sees
the definition.

I see, but I still don't get why this is worse than time ago, when the undefs where placed in the middle of stl_algobase.h and nowhere else. Do you?

Forgot: in fact, I don't see why the specific scenario above can happen: <limits> now includes c++config.h, which (now, not in old releases) undefs #min and #max again...


Paolo.
