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
