mwu, any reason we shouldn't do this? code size is the only thing I can think of

patch

Really really we shouldn't do this: 2-byte wchar is essential to making NS_LITERAL_STRING perform correctly, unless we're building using GCC 4.4+ which has u"" string-literal support.

we are using gcc 4.4
We shouldn't expect proper support support for short wchar_t on android. Their plan is to make wc* functions all use 32bit wchar_t. As long as we don't use the system string functions, we should be ok.

per discussion on irc, we should just ignore these warnings

patch to ignore warnings

WCHAR_CFLAGS is used only for the xulrunner pkgconfig info.  You probably want to also add -Wl,--no-wchar-size-warning to CFLAGS too.
