wide char support and -fshort-wchar option

[Mallikarjun Goudar]

Hi,
I would like to use wchar_t as unsigned short. I used -fshort-wchar
option to make this happen.
But i get following warnings when compile and link a test case.

'libc.a(ansi_files.o) uses 4-byte wchar_t yet the output is to use
2-byte wchar_t; use of wchar_t values across objects may fail"'

To resolve this, i should be rebuilding gcc libraries with -fshort-wchar option?

Please let me know.

Thanks,
Mallikarjuna
