Hello Guile hackers.

We are in the process of integrating GNU poke[1] in GDB by mean of
libpoke.

Problem is, libpoke uses the Boehm GC, as guile does.  We are working on
switching to an ad-hoc exact collector, but it will get some time.

So, in the interim, we may:

1) Make both libguile and libpoke to do GC_INIT conditionally, only if
    no one else has initialized the collector before.  This is already in
    poke master.  A suggested (untested!) patch for guile below. > [...]

#define GC_INIT() [...]

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