build failure mbstate_t not declared

Hi,
I checked out the latest buildroot and tried to build it but keep getting errors regarding mbstate_t not being declared. Here's a section of the output (there are many more lines with the same error, but I wanted to keep the post short.)
Any suggestions?
Regards,
Joe

Try building an existing board which is known to work.

$ make at91sam9260dfc_defconfig
$ make

Did make at91sam9260dfc_defconfig w/ the default setting everywhere except I chose 2.6.26 kernel and I still see the same results. Regards,

google -> mbstate_t is defined in wchar.h which gets included if you enable WCHAR.
You are sure you did not disable this in buildroot?

In my earlier build (rev 22508) yes I had it disabled.
But last night when I ran the "make at91...defconfig" (after doing "make distclean") it set BR2_USE_WCHAR=y
Does "make distclean" clear the previous toolchain?
Joe

Ok, I deleted everything under toolchain_build_arm and tried to make the at91sam9260dfc_defconfig again with 2.6.26 kernel.
I got an immediate failure that ftp://...2.6.26.tar.bz2 not found. (See snippet below)
So I selected latest stable kernel (2.6.25.10) and ran make again. This time had success!
So moral is "make distclean" doesn't effect the toolchain and they need to be removed manually.
Thanks,
Joe
