I guess that for glib these things are matters of degree rather than
principle. glib now uses gcc's constructor and destructor attributes
since, I think, version 2.32 (I believe that is when gconstructor.h
first appeared), presumably on the grounds that, although non-standard,
they are also found in most mainstream compilers likely to be used
with glib.
