Ok, thanks for your feedback. Indeed, the only possible "cause" of the problem
are the finer grained checks for wchar_t vs C99 wchar_t proper functions which
are now carried out after my 2006-05-03 commit (which fixed regressions on
solaris and hpux).
In fact, looking at the 20060428 log what was happening before the patch is
that ac_c99_wchar was "no" and then wchar_t ended up being *completely
disabled*. Currently, instead, the autoconf tests try to enable wchar_t support
(all the configure tests pass) but then something very misteriously fails at
build time.
All in all, waiting for someone to kick-in and shed some light about MIPS vs
MIPS64 and all that, you can certainly force by hand the old (4.1.0) behavior
by passing explicitely --disable-wchar_t at build time.
