Nothing, at least on OS X, it appears.

Another question might be "what do we have to change so that compiling 
with -pedantic doesn't produce any more warnings than compiling without 
-pedantic does?"  I've fixed some of the warnings, but not all - there 
are a bunch of warnings about converting between "char *" and "{guchar 
*, guint8 *, unsigned char *)", for example.

In addition, the configure script option that enables -pedantic also 
enables a number of other options, which cause other warnings, such as 
warnings about function declarations in system or third-party package 
headers that don't have prototype arguments.  There's at least one case 
where either a GLib or GTK+ header (I forget which) declares a function 
without a prototype (in a deliberate attempt to avoid function prototype 
checking), which produces a warning with -pedantic, at least with the 
compiler I have).  I think I've seen on at least some versions of 
Solaris declarations in X11 headers that have no prototypes.
