Re: sqlite3.c won't compile with -std=c89

The attached patch is an alternative way of solving this particular
problem.

[[[
Work around a problem on older OS X systems: sqlite3.c includes
<libkern/OSAtomic.h>, which uses 'inline' and thus cannot be compiled
with -std=c89 that we are using for all files.

* subversion/libsvn_subr/sqlite3wrapper.c
   (toplevel): Define 'inline' as '__inline__' (which gcc accepts even
in c89
    mode) during a pre-emptive inclusion of <libkern/OSAtomic.h>.
