Summary: 2.3a2 Sol8 make fails at _iconv_codec.

Initial Comment:
Python 2.3a2 build process fails during building
_iconv_codec
module. The message is;

[...]
gcc -shared
build/temp.solaris-2.8-sun4u-2.3/_iconv_codec.o
-L/home/inyeol/util/python/lib -L/usr/local/lib -o
build/lib.solaris-2.8-sun4u-2.3/_iconv_codec.so
Traceback (most recent call last):

  [... long traceback here...]

  File "./setup.py", line 209, in build_extension
    imp.load_dynamic(ext.name, ext_filename)
RuntimeError: can't initialize the _iconv_codec module:
iconv_open() failed
*** Error code 1
make: Fatal error: Command failed for target
`sharedmods'

My build environment is gcc2.95.3 with Solaris 8
linker.
I've built 2.2, 2,2,1, 2,2,2, 2,3a1 with the same env
and there
was no (major) issues like this. I attached my
configure and
make log messages.

These are just warnings, I see no error here. BTW the GNU
implementation does supports both ASCII and ISO8859-1 as
encodings, so I don't see why 1.12 should break anything

The fix applied to _iconv_codec.c (in version 1.12) *breaks* the 
extension unnder cygwin and possibly other systems that use 
GNU iconv instead of a native library (namely, Solaris and BSD 
derivatives). The relevant errors:

I changed the init function to use 'ISO8859-1' instead of
'ASCII' as the test encoding. Can someone test whether this
fixes anything?

In order to get the build to proceed, you can change line
210 of setup.py from:

        except ImportError, why:
to:
        except (ImportError, RuntimeError), why:

This is just before:
    self.announce('*** WARNING: renaming "%s" since
importing it' ...)
