According to the Boehm GC documentation, this 'conditional 
initialisation' is unnecessary:

/* Portable clients should call this at the program start-up.  More   */
/* over, some platforms require this call to be done strictly from the*/
/* primordial thread.  **Multiple invocations are harmless.**         */
#define GC_INIT() [...]

(emphasis added).
