With 1.48 on 64-bit Windows 7 and gcc 4.6.0, the following code fails to compile with -std=c++0x:
#include
int main(){} The diagnostics are:

Try compiling with -std=gnu++0x GCC's -std flag is a little confusing: * no -std flag means "C++98 with GNU extensions" * -std=c++98 means "C++98 with no GNU extensions" * -std=c++0x means "C++0x with no GNU extensions" * -std=gnu++0x means "C++0x with GNU extensions" So, if before you were compiling with no -std flag, and now you are compiling with -std=c++0x, then in addition to enabling C++0x features, you are disabling GNU extensions, which I'm guessing wasn't your intention. Now admittedly, Boost should work in the absence of GNU extensions, so there *is* a bug in either Boost or MinGW behind the scenes, but you have a workaround for now. Regards, Nate
