The attached patch avoids the error, though I'm not sure if it's optimal (it adds "#undef malloc" as suggested in the above bug report).

Compilation then succeeds, but make still fails due to some strange dependency issue with man-page generation:

====

Seems like "src/[" is not automatically built ?

===
$ ls -l ./man/test.td/\[
lrwxrwxrwx    1 agn      usr              38 Jan 28 07:25 ./man/test.td/[ -> /home/agn/sources/coreutils-8.25/src/[

$ ls -l ./src/[
ls: 0653-341 The file ./src/[ does not exist.
===

To solve it, I built "/src/[" explicitly, then "make" completes successfully.

===
$ make src/[
  CC       src/lbracket.o
  CCLD     src/[
$ make
(( completes successfully ))
===

After that few tests fail with 'make check', I'll send in a separate message.
