[uClibc] WCHAR in uClibc 0.9.21

[Wen Yang]

Hello,

I have just tried the 0.9.21 for the full Locale support.

When I compiled the libvmime using arm-uclibc-g++, I got two problems:

1. it complained about std::wstring not defined. I used a workaround:
add _GLIBCPP_USE_WCHAR_T to the DEFS of the libvmine Makefile
2. it complained about wcsftime not defined. Then I used anohter
workaround: in uClibc include/c++/cwchar, comment LINE 168 of "using
::wcsftime;"

Why would it give those errors? Would my workarounds cause any problem?

I am using the cross compiler of Toolchain GCC 2.3.2 based on uClibc
0.9.21. Before I compiled the toolchain, I did set the UCLIBC_HAS_WCHAR
to yes.

Here is the uClibc config file:
