I haven't found an email with a solution :-(. However, I looked into an
old version of this Symbian header file. There I found the typedef and
an interesting comment by the Symbian developers..
/* There seems to be a lot of nonsense about _need_wchar_t etc., but for
* STDLIB we have cut the Gordian knot and done the simple thing
In my opinion, cutting the Gordian knot was not a good idea ;-) as in
C++ normally wchar_t is a keyword.
BTW, g++ 3.3 also reports the typedef as an error:
limits.c:5: error: redeclaration of C++ built-in type `wchar_t'
As a workaround you can either modify this file (remove the typedef) or
create a modified copy that is locate in a directory, which is searched
first by ac++.
Maybe a macro would also help:
#define wchar_t symbian_wchar_t
Regarding ac++ we'll have to find out which compiler versions tolerate
such a typedef and if we can integrate this behavior, e.g. in the
