Sounds highly improbable.
I thought that the function definition style is just some syntactic 
sugar which cannot affect the way it is compiled.

why?
this is the standard way to handle calloc/malloc/alloca.

well, yes, I guess I can arrange for the gllib to be compiled with gcc.
more work for me - but what for?
why not just apply the patch?

I think there is some value in making gllib compilable with g++: better 
type checking for gllib maintainers and ease of maintenance for gllib users.
