The Mac build off of "master" fails for me currently in srfi-13.c,  
with the comparison-always-false warning Greg discussed.  I hacked  
around that, but then guile-readline doesn't build:

Making all in guile-readline

DHAVE_CONFIG_H  -I. -I.. -I../../guile-readline/.. -I../../guile-

../../guile-readline/../libguile/strings.h:26:21: error: uniconv.h: No  
such file or directory

Neither the path specified for libgmp nor the path specified for  
libunistring at configure time is included here.

I don't think any of this is Mac-specific; I'm surprised that it works  
on GNU/Linux systems.  Perhaps I'm building it in ways that are  
unusual for the other developers (build dir != src dir, libgmp and  
guile-1.8 installed in the same place, libgmp and libunistring  
installed in different nonstandard directories)?

If I use CPPFLAGS=... and LDFLAGS=... instead of --with-libfoo-prefix  
configure options to specify paths to find libgmp and libunistring,  
the tests still pick old, installed Guile headers (which this time  
I've poisoned to highlight the problem) from those locations instead  
of the in-tree versions:

lib.c:23:

I might be building Guile as part of a larger package  
(*cough*Emacs*cough*) that wants to include stuff from the same system  
directories (e.g., for MacPorts, pkgsrc, whatever) where an old  
version of Guile is installed, and thus Guile gets passed CPPFLAGS/ 
LDFLAGS settings that add that old version to the search paths.  So I  
think the CPPFLAGS/LDFLAGS version needs to be made to work, as well  
as the --with-libfoo-prefix version.

With the attached patch, I can get guile to build with CPPFLAGS= and  
LDFLAGS= ... someone more familiar than I am with automake will have  
to fix the guile-readline stuff.  Even with my patch, it fails its  
tests:

make  check-TESTS
Testing /Users/raeburn/dev/guile/git/guile/b3/meta/guile ...
with GUILE_LOAD_PATH=/Users/raeburn/dev/guile/git/guile/test-suite
ERROR: In procedure make_objcode_by_mmap:
ERROR: bad header on object file: "GOOF-0.6-LE-4---"
FAIL: check-guile

Still looking into that....
