[PATCH v2] sim: use socklen_t with accept()

[Mike Frysinger <vapier@gentoo.org>]

The accept() function takes a socklen_t, not an int.  Using an int causes:
dv-sockser.c: In function 'connected_p':
dv-sockser.c:273: warning: pointer targets in passing argument 3
                           of 'accept' differ in signedness

So use the same socklen_t detection code as gdb and convert the accept().

v2
	- pull in socklen_t configure checks as suggested by people

2010-03-30  Mike Frysinger  <vapier@gentoo.org>

	* configure.ac: Check for socklen_t.
	* configure, config.in: Regenerated.
	* dv-sockser.c (connected_p): Change addrlen type to socklen_t.

Note: this config.in diffstat is larger because the regen tweaked the
      comment style for a lot of defines ... not sure if this is correct
