--- Comment #4 from Giacomo Tesio <giacomo at tesio dot it> --- Indeed, this is a request for an enhancement, not a bug report. I mean, being able to decide how gcc defines wchar_t is an enhancement, given the poor definition of such type in the standard. With -Wno-pointer-sign one will miss useful warnings for pointer signedness unrelated to wide characters. Note however that I don't want to be able to redefine *any* built-in definition without warnings, just those three. To me, an even better alternative is: add a -funsigned-wchar to gcc to enable unsigned 32bit wchar_t. Something along the line of -fshort-wchar, but that change only the sign of wchar_t, not the size. Given that according to the unicode standard the width of wchar_t is compiler-specific, such a flag can improve the ability to use gcc for code developed with more exotic compilers and platforms.
