hmm, i'm not able to reproduce this.

the configure-script detects this as well:

now, the build-system simply ignores this failed test for "malloc" 
(which might be a problem in it's own; but then: if malloc() is missing 
nothing would work anyhow so we just fail a bit earlier).

i don't know why malloc cannot be detected in your build, but it works here.

i'm going to leave this open until autoconf-2.70 is in sid (just in case 
i got something wrong).
if you think the bug is indeed a non-issue, just close it ;-)
