Phil,

it seems that all the corresponding wchar functions are missing in the
Solaris 8 default installation:
config.h:/* #undef HAVE_VFWSCANF */
config.h:/* #undef HAVE_VSWSCANF */
config.h:/* #undef HAVE_VWSCANF */
config.h:/* #undef HAVE_WCSTOF */
This is checked in the configure script aroung line 20633.

It implies the ac_wfuncs variable to be set to no and therefore to exclude
wchar_t specializations (around line 20730).

To check the script execution I change the gobang line with:
#! /bin/ksh -x
export PS4="\$LINENO: "

I didn't find any information on how to complete the default installation
with these functions.
Can you provide me with any good (of course :-) advise on how to install gcc
3.2 with support of wchar_t specializations?
Should I install the glibc for Solaris 8?

Thanks
