[PATCH users/roland/gold-charnn] gold: Use char16_t, char32_t instead of uint16_t, uint32_t as character types

[Vaseeharan Vinayagamoorthy]

Hi,

Sorry for the delayed response.
Using -std=gnu++11 in our build scripts when building binutils does fix the issue for us, as mentioned in https://sourceware.org/bugzilla/show_bug.cgi?id=30867 .
However, does this need fixing in configure.ac instead?

Kind regards,
Vasee

I didn't realize that building gold with compilers so old they don't
support C++11 was supported.  The GCC source history suggests that
char16_t and char32_t support were introduced in GCC 4.4.  I'm not
sure when the default C++ mode was changed to be >= -std=c++11.  It
looks to me that the configure stuff should be making it pass
`-std=c++11` if that's required, but I don't know how that test is
coming out in your build.  I wonder if using `CXX=g++ -std=c++11`
makes a difference with your version.
