Building gcc to support wide-character operations

[Dale Peakall]

GCC: 3.1 20020510 (prerelease).

Any idea how I can compile a version of gcc/libstdc++
that properly supports wchar_t on Solaris8?

i.e. supports wcin, wcout etc.

Just changing c++config.h in the installed distro to
define _GLIBCPP_USE_WCHAR_T gets wcin, wcout etc.
defined but it appears that it's trying to bring 
various c-library functions not even mentioned
in the standard (i.e. vfwscanf, wswscanf, vwscanf,
wcstof, iswblank) into the std namespace.

I can't find any of these functions used by libstdc++
(although I may have missed something).

Commenting out these lines in cwtype and cwctype
allows the program to compile, but it won't link
because it appears libstdc++ hasn't compiled a
whole load of support code.

My code certainly doesn't want them.  But how do I
get the darn thing compiled to actually support
it?

TIA.
