And a bit more: "Constructor not supported on this compiler, linking in 
resources will not work"

Docs:

  If G_HAS_CONSTRUCTORS is true then the compiler support *both* 
constructors and
  destructors, in a sane way, including e.g. on library unload. If not 
you're on
  your own.

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

Any chance to become analogs to gcc's __attribute__((constructor)) / 
__attribute__((destructor))?
