Hello,
this problem was reported against gcc 3.1 which is now quite old. Would
it be possible for you to determine if this problem still occurs under
gcc 3.2.3 or 3.3 prerelease? Thanks,
Dara

Thanks for the feedback and analysis. Hopefully one of
the libstdc++ huys will take a look at this soon...

Before you try hacking around this yourself, it's useful to investigate
/why/ the autoconf scripts decided it wasn't possible. The file
sparc-sun-solaris2.8/libstdc++-v3/config.log in the build directory will
contain the output of the wide-character tests. Searching for "C99",
"mbstate_t" and "wchar" should give results.

We already try, thankyouverymuch. More specifically, others have reported
success on this platform, so I'm initially inclined to look at individual
platform problems than systemic bugs. There were problems with the 'long
long' tests under Solaris giving up too easily, but those were fixed back
in 3.0.3; wide character support is related but separate.

The requirements before libstdc++ will build with support
for wchar_t are too restrictive.
Changing cwchar and cwctype to not try import the missing
functions into std namespace and changing config.h and c++config.h to define _GLIBCPP_USE_WCHAR_T and rebuilding libstdc++ works without problem on solaris 8, although autoconf had decided that this wasn't possible.
Support for wchar_t is mandated by the C++ standard - gcc should make more extensive efforts to support it on any platform that it reasonably can (i.e. supports the set of functions used by libstdc++).
