Untested idea (not having the relevant system and time :(

AC_DEFUN(zsh_TEST_LIMIT_VALUE,[
echo > get-limit-value.c << EOF

main()
{
#ifdef $1
printf("%d", $1);
#else
printf("%d", -1);
#endif
return 0;
}
EOF

cc -o get-limit-value get-limit-value.c

val=`get-limit-value`
if test "$val" -ge 0; then
AC_DEFINE(ZSH_$1, $val)
fi
]

later on

zsh_TEST_LIMIT_VALUE(RLIMIT_AS)
zsh_TEST_LIMIT_VALUE(RLIMIT_RSS)
...

and in code use ZSH_... instead of original values.

Ugly as sin but it will work.
