Hi Dongsheng,
I don't see any occurrences of NULL in fpu-ia32.cc. Perhaps this is a bug in the <csetjmp> or related header file in your system?
When I use gcc 4.5 (version 4.5.3 20110221) with mingw-w64 trunk, after preprocessing, setjmp(env) extend to _setjmp3((env), NULL) .
When I use gcc 4.6 (version 4.6.0 20110221) with mingw-w64 trunk, after preprocessing, setjmp(env) extend to _setjmp3((env), __null) .
So gcc 4.5 run into trouble, but gcc 4.6 OK. I don't know why and how to fix in GCC or mingw-w64, but just add one line '#include<cstddef>' in the source is the simplest way.
