void __attribute__ ((__constructor__)) fct (void){...}
void __attribute__ ((__destructor__)) fct (void){...}
As I tested, Gcc 4.4.x on Ubuntu only supports the later form. While on Solaris, either SunStudio or Gcc (only 3.4.3 is available currently) supports both of them.
While there is a little different between SunStudio and Gcc, in case we declared two functions (let's say f1, f2) with attribute __constructor__, the call sequence would be f1 then f2 with SunStudio, but f2 then f1 with Gcc. However, the call sequence for 'destructors' is just the same -- f1 then f2.
