That is neither C nor C++.

Code

{ struct passwd*pwd(getpwuid(...));
  if(pwd)return true;}

is still compiled.

Code

if(struct passwd*pwd=getpwuid(...))return;

compiled too.

But 

if(struct passwd*pwd(getpwuid(...)))return;

will not.

Who is right?

G++ is right

a declaration in a selection-statement (if or switch) must be of the form:
  if ( type-specifier id = initializer )
or in C++0x:
  if ( type-specifier id { init } )

See 6.4 in the C++ standard
