Actually no. I'm building the entire thing. But those warnings come
form the glue libraries.

For what it's worth the Python bindings produce at least one warning for
me in the glue libraries:
/bin/sh /home/breser/wc/svn-trunk/libtool --silent --mode=compile gcc
-D_GNU_SOURCE -DSWIGPYTHON -g -g -Wall -Wmissing-prototypes
-Wstrict-prototypes -Wmissing-declarations -pthread -DNEON_ZLIB
-DNEON_SSL -DSVN_DEBUG -DAP_DEBUG -Wpointer-arith -Wwrite-strings
-Wshadow -std=c89 -I/home/breser/wc/svn-trunk/subversion/bindings/swig
-I/home/breser/wc/svn-trunk/subversion/include -I/usr/lib/swig1.3
-DSVN_SWIG_VERSION=103019 -I/usr/include/apache2 -I/usr/include/apache2
-I./subversion/include -I. -I/usr/include/neon -I/usr/include/apache2
-I/usr/include/apache2 -o
subversion/bindings/swig/python/libsvn_swig_py/swigutil_py.lo -c
In file included from /usr/include/python2.3/Python.h:8,
/usr/include/python2.3/pyconfig.h:856:1: warning: "_XOPEN_SOURCE"
<command line>:7:1: warning: this is the location of the previous

And even more if I actually do:
make swig-py

In the perl bindings case, things are the opposite, the glue libraries
are the warning noisy ones, the native stuff is very quiet.

The only thing I could do would be if we're using gcc just turn off the
warnings for that particular message, but I'm not sure I like that idea.
Plus it does nothing for people on other platforms.

At any rate per our agreement on IRC, we no longer build bindings stuff
by default.
