i came up with a small (haha) test program, which grows both env and arg sizes 
(or better: shrinks them until it works).

the output for interix is:

using sysconf...
max_arg: 1048576
env_sz : 3164
testing...
max_env with min_arg (4096): 60416
max_arg with min_env (4096): 60416
max_env with max_arg (60416): 4096
max_arg with max_env (60416): 4096
is max_env & max_arg together ok? NOT OK
is max_env / 2 & max_arg / 2 together ok? ok
---------------------------------------
limits: arg: 30207, env: 30207

(hehe peter, you where right ;) the 64K(+ some overhead somewhere?) limit is 
there).

on my linux box the same test yields:

using sysconf...
max_arg: 2097152
env_sz : 3955
testing...
max_env with min_arg (4096): 130048
max_arg with min_env (4096): 131072
max_env with max_arg (131072): 130048
max_arg with max_env (130048): 131072
is max_env & max_arg together ok? ok
---------------------------------------
limits: arg: 131072, env: 130048

the test program source is attached, could you have a look at it, whether you 
have some more ideas on this? it's just a quick-hack, so don't expect error 
handling, excessive comments, etc. ;p

thanks, markus
