I've tried to figure it out, but it is eluding me.

I can say it does not happen in a simpler testdir with just the putenv 
module, or putenv + allocator modules.

I assume you mean the preprocessed source? The above just reproduces the 
error message.

I've uploaded preprocessed (gcc -E) source:
http://jupiterrise.com/tmp/allocator.i
http://jupiterrise.com/tmp/c-strtod.i
http://jupiterrise.com/tmp/localeconv.i

Also, found one more include issue that I'd overlooked:
depbase=`echo dtotimespec.o | sed 's|[^/]*$|.deps/&|;s|\.o$||'`;\
        gcc -std=gnu99 -DHAVE_CONFIG_H -DEXEEXT=\"\" -DEXEEXT=\"\" 
-DNO_XMALLOC -DEXEEXT=\"\" -I. -I..  -DGNULIB_STRICT_CHECKING=1 
-I../intl -I/usr/tgcware/include -D_REENTRANT  -g -O2 -MT dtotimespec.o 
-MD -MP -MF $depbase.Tpo -c -o dtotimespec.o dtotimespec.c &&\
        mv -f $depbase.Tpo $depbase.Po
