Internal compiler error 252.

[Mike Danylchuk]

The following code causes internal compiler error 252 in egcs-1.1.2 and in
the gcc-2.95 development snapshot from May 24th:

typedef char TCHAR;
void main()
{
    try {}
    catch( TCHAR* Err ) {}
}

You can avoid the error by using catch( char* Err ) or typedef char*
TCHAR_PTR; ... catch( TCHAR_PTR Err ).

I've included the details from egcs-1.1.2 below.
