OK, well I don't think it'll break Linux, and the Mac uses a different
code path anyway. My main concern is with Solaris, but that port seems
to need some attention at the moment anyway, as it's trying to use GCC
flags that don't work on S10/Sparc, and SunStudio is linking png2c
with libpq.

Please commit, and I'll look at the solaris issues.
