libsigc++ 2.2.0 Build Failure Using Sun C++ Compiler.

[Elaine Xiong]

Hi,

I can't build libsigc++2.2.0(the previous releases are okay) with Sun
C++ compiler(CC). It seems the latest release includes code snips that
not supported by libCstd, which is the default C++ standard library. The
code snips are related to "iterator_reverse" and "iterator_traits". The
former one has different implementation compared to standard C++. The
later one is not defined in libCstd. I tried to write a patch to
workaroud them and attached it in this mail. Could anyone help me to
review it and checkin ? I would appreciate your any instructor and quick
response.

Best Regards,
Elaine

Great. What version of Sun's CC are you using?

Did this patch fix the build for you? If so, could you attach it to this
bug, please?
