I'm a bit curious what exactly is disallowed? Is it the late declaration 
of free_min_ptr? Or is it int min_slots_i = atoi(min_slots_ptr)? It's 
been along time since I had to use a c89 compiler :-)

OK.

But I was more interested to hear an opinion on the nature of the patch. 
And whether something like that could be included in 1.8.3 and 1.9. Not 
everyone has the chance to recompile in the environment in which his 
server apps are runnning. And most ISPs are reluctant to apply patches, 
which aren't official.
