Hi,

there are still C99isms in strings.c and threads.c.  I've attached a 
patch that changes the relevant code so that it can be compiled with 
GCC 2.95. IMHO C99isms ought to be avoided as long as Debian Woody and 
OpenBSD 3.5 are supported products since both distributions come with 
GCC 2.95 as default compiler.
