Still, I don't see how you can get a conflict with <stdlib.h> if the test
code does not include <stdlib.h>, and your report is very vague.

Can you please give a reproducible test case? This means,
  - Show a configure.ac that leads to the conflict.
  - Which autoconf version did you use?
  - Show how you invoke configure?
  - Which compiler is being used?
  - On which platform is this (FreeBSD, NetBSD, OpenBSD)? and which version?
  - Did it say "checking for alloca... yes" or "checking for alloca... no"?
  - What error messages did you see, from which tool, at which step?
  - Did you get a conflict in your program, when it included <stdlib.h>,
    after configure had run?
