Glib/gtk is full of macros. I believe que a C compiler is the right 
place to this kind of unsafe code. If i want create safe code i have 
c#,c++, JAVA, D or VALA.
Using macros is the only way to ensure intermediate APIs don´t have any 
overhead. Besides modern GUIs have support to understand what we have in 
a MACRO. Visual c++ have that kind of support.
