[postgis-users] osx make failure & shared libs for lstdc++

[Byron Amerson]

Hi  there,

I finally got some shared libs for libstdc++ for mac osx10.3, which are
not supported in mac's gcc-3.3. I had to build them myself from gcc-3.4
source code. Thanks to Benjamin Kosnik over at the libstdc++ list for that
tip.

So I built postgresql-7.4 against these new libs.  And now when I run make
on postgis-cvs(12-10-03), make breaks with the following error:

I am not savvy enough to know if this is related to the libstdc++ issue or
not.
