While using the compiler I discovered the following two problems: 1) The sample program ... an output like `SIZE: 4', but actually, the program doesn't compile at all. #include <stdio.h> main() { printf("SIZE: %d\n", sizeof(typeof(* typeof(int[3]) ) ) ); } Starting the compiler with: bin/g++ demo.cc -o demo results in the following error message: In function int main (): demo.cc:5: parse error before `)' Correct. TYPEOF can only be used on expressions. Since * typeof (...) yields a type, TYPEOF cannot again be applied. 2) Initializing a struct parameter with a default value doesn't work, though I could find nothing in the documentation which tells me that this is not supposed to work. The following sample program #include <stdio.h> struct example { int a; float b; }; void dummy(example demo ={5, 3.1415}) { printf("Result: %d %f\n", demo.a, demo.b); } main() { example yyy; example xxx = {1, 1.0}; dummy( yyy ); dummy(); dummy( xxx ); } This was a bug. It is now fixed. Thomas Kunz XITITKUN@DDATHD21.BITNET Michael
