Bisect showed that if I go back to v1.4.14, the errors persist. Bisect of gnulib/ subdir converges at commit 723fc0b7b3a5d770a48945c1e1bca262a4c2615a which is the "Use modern idiom for malloc() replacement." patch in http://lists.gnu.org/archive/html/bug-gnulib/2010-06/msg00176.html (all errors stem from this patch). I see that confdefs.h before contains '#define malloc rpl_malloc' and doesn't afterwards, but no other changes in the output section of the respective config.log files. Assuming that the stdlib.h header logic is correct, my next best bet would be that some source doesn't actually get to see the replaced header, but can't find any instances of that right now, and it's late ...
