This doesn't seem to do much for me, they don't seem to end up in the args 
passed to g++. I'm no Makefile wizard, so I got notmuch finally compiling by 
simply copy/pasting the ${strndup} and ${getline} from Makefile.config to 
Makefile:

# Now smash together user's values with our extra values
override CFLAGS += $(WARN_FLAGS) $(extra_cflags) -Dstrndup=_notmuch_strndup 
-Dgetline=_notmuch_getline
override CXXFLAGS += $(WARN_FLAGS) $(extra_cflags) $(extra_cxxflags) 
-Dstrndup=_notmuch_strndup -Dgetline=_notmuch_getline

[notmuch] [PATCH] Add tests to configure script to detect strndup and getline

[Jeffrey C. Ollie]

Add some simple tests to the configure script to detect strndup and
getline.  It's not important that the tests run, just that they
compile and link without any errors.
