My preferred solution to bug 627423 involves defining a destructor function from a macro.

gconstructor.h says:

  Some compilers need #pragma to handle this, which does not work with macros,
  so the way you need to use this is (for constructors):

  #ifdef G_DEFINE_CONSTRUCTOR_NEEDS_PRAGMA
  #pragma G_DEFINE_CONSTRUCTOR_PRAGMA_ARGS(my_constructor)
  #endif
  G_DEFINE_CONSTRUCTOR(my_constructor)
  static void my_constructor(void) {
   ...
  }


Which obviously won't work out for me from a macro.


Looking into it, I see two cases that this is actually used:

/* Visual studio 2008 and later has _Pragma */
/* Pre Visual studio 2008 must use #pragma section */


and...

#elif defined(__SUNPRO_C)
#define G_DEFINE_CONSTRUCTOR_PRAGMA_ARGS(_func) \
  init(_func)




For Visual Studio pre-2008, I see two possible solutions:

 1) stop caring

 2) Visual Studio is actually a C++ compiler, right?  It's pretty easy to
    get a destructor function called in C++ without using pragmas...


For the SUNPRO_C case is it possible that we could use _Pragma?  Is this the same as the modern Sun compiler or some old version?  Is there another way?
