__DARWIN_ALIAS is defined as:

__DARWIN_SUF_UNIX03)

__DARWIN_SUF_UNIX03 is defined as "$UNIX2003" for 32 bit builds.

Fortunately, most function replacements in gnulib are now done by
including the original system header and then only doing the
 #define func rpl_func
Only those replacements that use the old idiom of putting
 #define func rpl_func
into config.h are affected.
What's the extent of the problem? The following functions are using the 
__DARWIN_ALIAS or similar macros:

Out of these, the following are defined with #define in <config.h>:

 realpath
 mktime
poll # not a problem since gnulib's poll.h does not include <poll.h> 
 putenv
regcomp # not a problem since gnulib's regex.h does not include <regex.h> 
 strtod

Can you please check these functions by doing
./gnulib-tool --test --with-tests canonicalize-lgpl mktime timegm putenv strtod
? Please show the "configure" output as well as all errors shown by "make -k".
We only saw problems in putenv, when it first came up I was quite worried that the issue was widespread, but could not tell this list due to non disclosure agreement. It seems that it is not as big a problem as I had first assumed.
All the tests pass. This is probably because the testsuite does not seem to use the functions at all (probably why you asked for the configure output). 

Test output:
PASS: test-alloca-opt
PASS: test-canonicalize-lgpl.sh
PASS: test-malloca
PASS: test-stdlib
PASS: test-time
PASS: test-unistd

So, if the functions that do #define foo rpl_foo are modified to use the new method of including the system header and then #defining, I think the problem will go away. 

Thank you very much,
Peter
