changing typedefs of XMLCh gives errors.

[Abhi <at...@Adobe.COM>]

Hi all,

I am having some problems with the wchar_t typedef for XMLCh on Solaris 2.6 
using gcc 2.95 compiler. When I try to assert the XMLCh size (which is 
typedef wchar_t ) with another typedef which is *unsigned short*, I get 
assertion failure. So, when I change the typedef of XMLCh from wchar_t to 
unsigned short (which should be equivalent) in the file GCCDefs.hpp, I run 
into a problem while compiling. I get an *out of virtual memory* error. And 
this error is coming from the equal() function in HashBase.cpp.

Obviously, it seems, unsigned short and wchar_t do not have the same size 
on Solaris. But, I can't figure out the reason behind *out of virtual 
memory* error.

Thanks,
Abhi.

If the compiler is compliant, wchar_t and unsigned short are not equivalent,
though they might happen to be the same size. wchar_t is supposed to be a
unique type of its own, and can be whatever size the implementation chooses,
though it would be kind of silly for it to be less than 2 bytes in sizes,
since it wouldn't be very wide or very useful otherwise. On compilers that
aren't compliant, they will use a typedef, usually to unsigned short. But it
could be a 32 bit value as well.
