Hi guys,
during recent research concerning wchar_t and the related functions in our
libroot, I have learnt that haiku's current compilers define wchar_t in a way
(short unsigned int) that's incompatible with the actual implementation
(which expects it to be 32 bits wide). This causes most wc-related functions
to simply fail.
Locally, I have changed our gcc-configurations to break with
BeOS-"compatibility" and defined wchar_t as "long int". This made quite a
number of functions work all of a sudden (most notably, the conversion
functions between multi-bytes and wide-characters).
While this is good, applying this change will require every haiku
installation to be rebuilt completely. Additionally, all optional packages
which might make use of wchar_t in any way, would have to be updated, too.
So, is there a good/bad time for this or should I just proceed?
cheers,
Oliver
P.S.: if there are any changes pending for gcc2 or gcc4, please tell, since
now would be a very good time to apply those, too :-)
