wstring in gcc3.2.x on solaris

[Christina Wang]

Hi,

Thank you all for the suggestions. Finally I'm able to build gcc3.2 with 
wchar support on Solaris8 by editing acinclude.m4 under 
.../gcc-3.2/libstdc++-v3 and several other header files. Also I'm able to 
link with static libstdc++ successfully for all my shared libraries. After I 
build the new gcc-3.2 with the changes I made, I need to re-build it again 
using this new compiler as the bootstrapping compiler.

Christina
