c - Compiler support of GNU Statement Expression

Question

Which modern compilers support the Gnu Statement expression (C and C++ languages). What versions should I have to use a statement expressions?

Statement expression is smth like ({ code; code; retval }):

int b=56;
int c= ({int a; a=sin(b); a})

I already know some such compilers:

• GCC >=3
• Clang/LLVM >= ?
• Intel C++ Compiler >= 6.0 (Linux version, check page 4; bit limited)
• Sun Studio >= 12 (New Language Extensions)
• IBM XL for z/OS (marked as IBM extension)
• Open64 (as it uses osprey-gcc frontend)

This compiler seems not to support this (i'm unsure):

• MS Visual C++

PS. some C/C++ compilers are listed here but I interested only in mature compilers, that are used widely (e.g not a tcc or turbo c)
