Eric,
Is this patch OK? I find it hard to believe that WCHAR_SIZE is ever
64 (the iris5.h used to have 64, but a while ago David Billinghurst
fixed that and made it 32). If it is, then currently we can't support
cross-compilers properly, and maybe I should downgrade this error to
a warning?
Neil.
* config/mips/mips.h: Set MAX_WCHAR_TYPE_SIZE to 32.
