There are additionally patches on 'next' and more in the pipeline on 'pu'
which adjust these feature macros when compiling on Solaris.  See the
bc/solaris series 8fccb00 which was merged to 'pu'.

Also, if you happen to be using the Sun Studio suite 12 with c-compiler
version 5.9, I'd be interested to know whether you can compile diff-delta.c,
or whether you get an error (see commit 203ee91f).
