Is it a valid C++ structure initialization?

["Sergey Okhapkin" <sos at prospect dot com dot ru>]

Here is a test program (wich seems to me incorrect):

struct asd {
 int a;
 char b;
};

void f(int i, char c)
{
 struct asd qwe = {
  a: i,
  b: c
 };

}

The program compiles fine with gcc-3.2. Gcc 3.3 current snapshot reports:
test.cc: In function `void f(int, char)':
test.cc:11: error: too many initializers for `asd'

Solaris compiler complains:
$ CC -c test.cc
"test.cc", line 9: Error: a is not defined.
"test.cc", line 9: Error: Unexpected ":" found.
2 Error(s) detected.

The reason I'm asking about is that such kind of structure initialization is
used in cygwin sources (fhandler_socket::readv/writv, syscalls.cc
readv/writv, a whole bunch in wincap.cc). gcc 3.3 fails to build
cygwin1.dll. And I agree with the compiler. Removing "fieldname:" makes all
compilers happy.
