It doesn't need to be a AC_TRY_RUN, AC_TRY_LINK should be sufficient  
for this test. I do a cross-compile to build multi-way binaries on OS  
X, so this hunk leaked into the patch from there. You are right, it's  
not related to the srcdir/builddir portions.

I did it this way in preference to adding $(srcdir) a lot of times. I  
could split this into a separate patch, though.

Hmmm. I just checked quickly and didn't see what you are referring to.  
The changes in config_mk.pm to emit makefile comments are deliberate,  
and I'd like to keep them.

Maybe. I don't know of a portable way to do conditionals across make
